DES ALLEMANDS – June 14, 2012

DES ALLEMANDS – June 14, 2012

I am pretty sure this was our largest group to date at Spahr’s and at the lights. Maybe a combination of having to reschedule the May trip, an expanded number of invitees, and summer freeing up kids’ evenings all contributed to this. But in any case, we seated nearly 30 people at the restaurant, and just over 20 were at Cypress Point.

Given the rainy weather and Gordon’s schedule (and mine), we decided earlier in the day to only set up one light (mine) and waive the boating option. Rainy had persisted until dinner, so flight was expected to be weak and generally lived up to this poor billing. That said, the 7 young kids who came all had a lot to see and enjoyed themselves.

Of special note is that three people on this one evening were stung or bitten by something. A single bite to the ankle, multiple bites on a neck, and a single bite under the shirt to the lower back area occurred in that order and over the course of about 2 hours. Mostly likely culprit seems to have been a corsair, but I ask you: what are the odds of getting bitten by an assassin bug at all if you are not pinching it in your fingers, let alone multiple bites to different people on a single night AND when we saw not a one on the sheet?! Last Mon. (3 evenings before our outing) I collected with 6 entomologists from out of state, and we got 4 or so corsairs off the sheet; and out course no one was bitten save the one guy who opted to hand-collect!

Except for a huge number of some micro-lep species, this night was about 1/50th of Mon. the 11th. Still, not a total bust!

DES ALLEMANDS – June 11, 2012

A group of visiting entomologists, true bug enthusiasts and kids at heart for sure, from various parts of the country were in town for a technical committee meeting for the pest control company, Copesan. Including two of us from the Insectarium and Gordon Matherne, our group totaled 9. Dinner at Spahr’s was late owing to traffic woes, but we’d have been out late regardless – it was a terrific night!

As per usual, we set up UV and MV lights in two spots and also did some boating (I did not, and Gordon reported no efforts towards water scorpions). The flight was great, as was the perusal of grasses and weeds near the back boat launch.

30 dragonflies (a few at the lights, most from grasses)
20 medium-sized brown click beetles
~20 tiger beetles (T. carolina)
3 false bombardier beetles (we also a couple of true bombardiers)
1 Calosoma scrutator (yay!)
2 nymphal Carolina manitds
~50 cuban roaches
~6 Lethocerus
PDBs – 72
WSBs – 240
~30 Obscure bird grasshoppers (all nymphs)
~20 Oblong-winged katydids (all adults), including 4 yellow ones!

The flight was superb, and everyone was quite pleased. We did not get too many moths, though a few tiger moths and sphinx moths came in (very few). Walking along and hunting for orthopterans and odonates also revealed a host of other g-hopper and katy species and a slew of orb weaving spiders. Of these, the young Argiope and Nephila impressed, but most exciting was the number of starbellied orb weavers, Acantapeira stellata. Neat bugs! We also caught a few corsairs, one of which tagged a collector’s thumb. Effects (pain, which lessened with time) lasted about 4 hours.

MANCHAC - May 26, 2011

Six of us went to the Manchac Swamp area (including Joyce WMA) on 5/26/11. The drought manifested itself in some noticeably low water in some places (Joyce was about 4 inches down), and there was, for whatever reason, a dearth of certain things we tend to find in good number come late May: butterflies (saw 3 total, of which 2 were dead), wasps, grasshoppers, and the “widow bridge” produced not one such spider for the first time in my experience.

We were able to collect about 50 dragonflies (for cooking at Bug Appétit) and 75 or so lubber grasshoppers to be used on display and at IRF for breeding. We got a pair of wheel bugs, some large bagworms, a few pretty barklice, and an uncommon biting midge that is red and sports long back legs and thickened front leg tarsi. Aquatic collecting was poor (10 whirligigs, 2 water scorpions, and a lone dragonfly naiad), and we did not bust any logs; this may have resulted in a mutiny were it not for a good lunch!

Also of note: 11 ant species, including all three Pseudomyrmex found in LA, a large number of young black and yellow garden spiders, a couple of wolf spiders of 2 species brought back for presentation, a pair of field crickets for the Café table, and a terrific little beetle sometimes called the Delta Flower Scarab (Trigonopeltastes delta).

BUGSTOCK 11

These are just a few highlight photos (until later...) from 'stock 11....first and foremost I want to thank Sr. Juan and Miss Stephanie for once again hosting this symposium of multifarious interests and continuance of documentary practices. I have always been proud to proclaim that I am an "adopted" part of the Family...and being that most of my kin still resides in the Greater New Orleans area, they mean a tremendous amount to me. Secondly, saludos to the Finchmeister and Eric the BlackSmith (no, really....he is an experienced Blacksmith and his last name is Smith) for taking me hostage and going forth with this pilgrimage to the Stock o' Bug....whilst en route we captured a fleeing Greg and brought our team to WAL*MART (it just looks better when I spell it in all caps...) and purchased a wide variety of random items.....except Eric's television.....the rest.....is history and another round of great memories.


First off is a male Triorla interrupta with a Diogmites angustipennis kill.





Below is a Mydas clavatus that was very cooperative at the second gate.





.....and before I hit the hay tonight...one more: Laphria lata with a shield/stink bug sp. kill....

2010 Vacation - Part Two

The next day (8/4) we made it over to Natchez and drove around town quite a bit.

We visited the Melrose Plantation (somewhat by accident..)

got a good view of the Mississippi..

then got on the Natchez Trace parkway.

The first visitor info stop we encountered had a small grave yard behind it.

2010 Vacation - Part One

This year we took a camping trip up through Mississippi. The first night, 8/3, we spent at Homochitto National Forest.

(The drive up)

It was dark and late when we got there - we setup the tent and got a fire going.

(The next morning)

The next morning we found a really nice lake with a recreation area there, but it started pouring rain not long after we got out of the car.

A.I. staff field - Louisiana Nature Center 5/19/2010

On May 19th, we made a trip to the Audubon Louisiana
Nature Center (Zack plus 5 in the morning, only 2 could stay through the afternoon).
The site was flooded badly during Katrina; buildings are decrepit; remediation
has been done on the grounds (which total 85 acres of mixed bottomland hardwood
and swamp) such that the blackberry and tallow are not the sole plants on site,
thank goodness. That said, it was nice to have a little blackberry around...and
by that I mean the picking was extraordinary. We brought home plenty.

As for bugs, we collected a large number of pill
bugs and several greenhouse millipedes for our “rotten log” exhibit in the Insectarium’s
Louisiana Swamp gallery. We also brought in about a dozen large slugs for a
display in our Main Hall focusing on non-arthropod invertebrates. A few patent-leather
beetles and giant water bugs (Belostoma sp.) rounded out the stuff we took to
the Insectarium.

Diversity was pretty good considering what took
place on site in the late summer of 2005. A partial list is below. We found
2 juvenile wheel bugs with prey (images attached). In one instance, a ladybug
is the meal. In the other, an ironic twist as the insect being sucked on is
itself a predatory stink bug (subfamily Asopinae).

Spiders – 12 families (either web only or spider itself), including
the well-camouflaged trash-line orb weaver (Cyclosa sp.) and a feather-legged
spider (Uloborus glomosus).

Dragonflies – 6 species, including the gorgeous Carolina saddlebags

Lepidoptera – lots of giant swallowtails, a gulf fritillary, a viceroy,
a grape leaf skeletonizer, and a noctuid of some sort rounded out the adults.
Larvae consisted of a few salt marsh tigers and fall web worms and one pink-striped
oakworm.

Hymenoptera – not much ant diversity (result of flooding?), bumble bees,
carpenter bees, honey bees, leafcutter bees, and a lot of wasps of many species
(vespids, and sphecids mostly). Someone found a sawfly larva, too.

Beetles – Here again, the lack of numbers and diversity may be partially
a post-flood result. Patent-leather beetles (more larvae than adults); many
click beetle larvae (and one adult of a smaller species); a couple of larger
bombardier beetles (Brachinus sp., I think); ladybugs; a couple of un-IDed ground
beetles; a hardwood stump borer; a nice lepturine longhorn beetle (wasp mimic,
visiting lizard’s tail).

Others of note – a two-striped walkingstick, adult spittlebugs, a pale-bordered
field cockroach (which were occasionally easy to find on grounds), lots of stink
bugs of one species a well as at least two others, some katydids, a couple of
different assassin bugs, a nice, large Tabanus atratus, only one deer fly (thank
goodness), a mercifully light load of mosquitoes, and a pair of different carne
flies (one was quite long and thin, even by this family’s standards – did not
get a close look at it).

Pearl River + Honey Island Swamp 5-8-2010

Pearl River/Honey Island Swamp May 8, 2010 field notes:

The day began with light drizzle/mist but finally cleared up before noon. Many
roadsides at front gate had been sprayed with herbicides. Self-heal, Prunella,
was blooming everywhere. Host plants-passion flower and cassia- were beginning
to sprout by the railroad tracks; but, no butterfly eggs yet.

Mahaw berries by shooting range.

Multiple baby Lubber grasshopper migrations on each trail.

Not many predator dragonflies hunting. Overall delayed activity due to cold
winter and cool spring. Delighted to see 4 gorgeous Indigo buntings!

Combined reports:
4 Pipevine Swallowtail
1 Giant Swallowtail
4 Tiger Swallowtail
16 Black Swallowtail
4 Palamedes Swallowtail
3 Spicebush Swallowtail
2 unidentified dark swallowtails

A.I. staff field trip to Audubon Zoo

This is a late report on the staff field trip from last week to Audubon Zoo.

We got a late start on account of a meeting, but we were at our red-tip cutting site by the Zoo's perimeter fence in time to catch up with staff from Mosquito Control and Jerry Howard of UNO. I think they'd already been looking for trap-jaw ants at another site or two on Zoo grounds, but now they were upon the colony I found in Feb. To make a long story short: we spent about 30 minutes there, but the good part was that the head tree guy at the Zoo, Daniel, showed up with a chainsaw and cut the railroad tie in which we hoped most of the ants and the queen might be. And in fact both the look of the wood and the lack of ants to be found in the surrounding soil makes us think we succeeded in getting the bulk of the colony and the queen. I plan on emailing Jerry Howard in the near future to check on the ants.

Our next stop was the Swamp exhibit, where we first met up with Cathy Landry - she was feeding 4 downy woodpeckers she managed to save (orphans), and the whole scene was pretty neat. After chatting with the rest of the staff, we went dip netting at a couple of sites. Several interested zoo visitors stopped to ask us about the activity, and I commend the trio of us for our enthusiasm in explaining stuff, showing bugs off, and talking up the Insectarium!

The day's take included several aquatic plants that I hope were of use in exhibits and also the following:

- dragonfly naiads (10 or so)

- Belostoma (8 or so)

- predacious diving beetles (only 2 or 3 adults, but we sure found a lot of their larvae - makes me want to black light there at some point later this summer!)

- spicebush swallowtail caterpillars (6 or 7)

Species Survival Center - 5/5/2010

Folks usually want to know what we encountered on our field trips. This is probably
the best way to be sure everyone gets an update of sorts.

Species Survival Center, 5/5

In spite of it being Cinco de Mayo, we did not see any bugs drinking beer while
we were traipsing about in the West Bank woods. But we did see or collect quite
a number of neat things. Among them:

Hymenoptera -
- Many carpenter ant queens (kept 7) and workers (kept about 12-15 for presentations)
- In addition to the ubiquitous (if not universally loved) fire ants, we saw
about 5 other ant species
- Found a queen yellow jacket in wood, and saw 2 others in flight. The former
has now happened a few times at SSC for me, but I'd never seen one flying about
- The number of newly-started paper wasp colonies on buildings was really impressive,
especially in crane (bird) stalls. See note below about these stalls.
- Honey bees all over the blooming privet

Coleoptera -
- Dead triceratops beetle Phileurus valgus outside staff building
- Several click beetle larva, one of the eyed click, Alaus oculatus, and a wiggly
pupa
- un-IDed ground beetle larva (found 2 in rotten wood) with nice sclerotized
banding on the dorsum
- 8 or 9 patent-leather beetles (added to Bait Shop)
- Small pleasing fungus beetles (I think a Triplax species) in some shelf fungus

Diptera -
-1 male and 1 female robber fly of the genus Laphria
-Soldier flies on good number at a manure-rich compost pile along South Bunker
Road (genus Hermetia)

Lepidoptera -
Sighted (none in great number): hackberry, question mark, fiery or whirlabout
skipper, snout, American painted lady (probably), a few small leaf-mimic moths,
and one slat marsh tiger larva

Spiders -
Azilia affinis, a rarely encountered spider in this part of the world, it
is usually associated with cave entrances

Sphodros rufipes, a fantastically interesting purse web spider which I thought
we gone from a previous spot - great to know they are still (or once again)
there

Acanthepeira stellata, a very attractive little orb weaver
Leucage venusta
Verrucosa arrenata
Argiope aurantia egg sacs
Other araneids too young for ID
4 wolf spp.
2-3 salticids, incl. a male T. sylvana
Ant-mimic (genus likely is Castianeira)

Other -

- Rosy wolf snails (2 young) and an assortment of other snails and slugs
for exhibit

- In rotting wood - we busted open a fair bit - we found 2 of our native Scolopendra
sp. and one each Vonones ornata and Vonones sp. (both harvestmen, the latter
quite pretty). Brought back a good bit of wood for use at the Insectarium.

- The small wooden entry ways (stalls) into fenced in crane enclosures are
interesting little microhabitats. They are loaded with old nests built by at
least 2 mud dauber species; they house jumping spiders, cellar spiders, and
occasionally large fishing spiders (though we did not get any on Wed.); black
and yellow garden spiders leave egg sacs in the stalls, and Carolina praying
mantids leave oothecae there as well. We collected about a dozen mantid nymphs
(at IRF now) that were part of a large batch that had clearly emerged from their
eggs quite recently.

April 18-20, Grand Chenier, LA

James Beck is a birding demi-god! He was the “guide,” Zack Lemann the host, and three other folks came along as well. The idea was to show some Yankees (nice ones, actually) what quality bird watching is all about. We hit the spring migration at its peak and catalogued well over 100 species. This is not the best forum in which to detail all the particulars, but I’ll say this: terrific birding, near-perfect weather, no mosquitoes, great company!

Along the way, there was some bug hunting (surprise!) initiated by Zack. We found black widows in the field in large numbers at Johnson Bayou. All were residing in dead trees. We collected three nice females.

Butterflies were in short supply, but Phaon crescents and giant swallowtails to the tune of about 5 each were spotted along with a couple of sleepy oranges and two other swallowtails that I think were blacks. (Serious drought is in effect in SW Louisiana.) Plenty of damselflies if you looked for them in low vegetation along the cheniers, but almost no dragonflies. Carpenter bees in good number concentrated at certain trees, no other flighted hymenoptera of note. Got one eyed click beetle from a rotten log! I’ve not had time to look at Wagner’s caterpillar guide yet, but the hackberry trees were absolutely littered with a geometrid larva of some sort.

Back in Grand Chenier, we set up a 150-watt MV light and a 15-watt UV 2 nights in a row. Very similar insects both nights, but substantially more on the first evening. I’m not sure the weather or moon were different enough to account for this disparity, but I don’t have a good explanation. Gobs of water boatmen and substantial numbers of several other types of beetles: smaller hydrophilids and dytiscids, rice and sugar cane beetles (both scarabs), rove beetles, and a pretty good carabid mix, including bombardiers, false bombardiers, and quite a few others. Moths were mostly small, but some tiger moths and a couple of carpenter moths came in, along with about three fishflies (all female) over the course of our two evenings.

The most exciting find among the bugs was…a large payload of pleasing fungus beetles (Megalodacne sp.)! This is a beautiful beetle, but they are not often collected. If it’s been wet, they are spread far and wide over rotting wood that has their host fungus on it or nearby. But in winter or times of drought (did I mention it was dry?), they cluster under bark. Well, we found some bark, and we found some beetles! I am waiting on a hard count, but I believe it’ll
come in above 50! They are now at the Insect Rearing Facility of Audubon Insectarium.

Vermilionville / BVD - 7/29/09

Michael, Emma and I set some banana/sugar traps near the BVD today. Here is a pic of the find that was the reason we set the traps:

I spotted this guy (below) near the trash cans. I know it doesn't look very appetizing but you will have to trust me that it is a moth pupa:

Vermilionville / BVD - 7/28/09

Yesterday Michael and I poked around Vermilionville and the BVD after work. We found: 1 larval cacada looking for a spot to moult, 1 ball of dirt that looks suspiciously like a dung ball, an apparently sick bat near the base of a tree and 2 buprestids on a persimmon tree trunk.

Des Allemends trip - 7/21/09

    Here is the count from last night's haul (excluding some of those bugs ofwhich we got just a very few):

Crickets - 35

PDB's (predacious diving beetle) - 59

WSB's (water scavenger beetle) - 38

Belastoma - 29

Water scorpions - 86

Lethocerus - 74

Dragonflies - 91

Fishing spiders - 3 (2 of these are the smaller species we use most often,but 1 is a large but thin female of Dolomedes tenebrosus. She's at IRF and,we hope, getting fattened up.)

Very productive and fun night. Hope y'all had fun!

Alexandria & LeCompte 20/21 June 2009

Well.......Steve, Travis & I made a nocturnal run up to Alexandria to set up lights at my friend Roger Breedlove's house. We set up the rigs, and figured on driving around, checking out the local gas stations (more specifically their lights...). We found a moderate number of ox beetles, Strategus aloeus, mostly minor males & females, but a few major males tossed in for fun.

We also had at least one grapevine beetle, Pelidnota punctatus

There were a few Calosoma sayi specimens crawling around......

It was an overall dry run....in more than one way......it hadn't rained in a while....and unless Strategus is your only bounty........dry run fits there as well. Oh well.......next time!

Mini-explosions from the Asilid World!!!

Man......if it gets better than this.......I don't know if I can maintain further composure!!!!

While watching the sun set the other afternoon, Ellen pointed out a remarkably beautiful, albeit miniscule dipterid just inches away from where we were sitting. I squeezed off a couple of pictures, and soon forgot about it......I dunno, I was chasing a wasp or something.........

So when it came time to upload the photos from my camera to our PC, there was something amiss. I initially passed this fly of as a Syrphyid fly of some sorts...........stupid ME.

Ellen insisted that it was a robber fly, so I sent the photos to Zack, who was so bold as to "bet money" on Asilidae. Now I was really intrigued........and super excited that my baby had potentially keyed out something pretty cool. The text below is from Gayle & Jeanelle Strickland:

"Congratulations to Ellen!! Not only is it an Asilid, but an excellent record. We think it is Atomosia sayii. Images of the genus Atomosia may be seen on Herschel Raney's website.
Click on the following link and scroll down to the last two photos which are A. sayii.
http://www.hr-rna.com/RNA/Main%20pages/Laphriinae%20frame%20page.htm
A similiar species, Atomosia rufipes has a bit of black on the legs. To see a photo of A. rufipes, click on the following BugGuide link.
http://bugguide.net/node/view/89837
Note that it is an excellent match for yours except for the touch of black on the legs. There are no images of A. sayii on BugGuide. I suggest that you tightly crop the images and submit both of them to BugGuide. The photo of A. rufipes is a good example of desired cropping.

Gayle"

WOW!!!!!!!!!!

So below are two images of the Atomosia sayii, followed by a couple of A. puella I found around the yard today............ -j

Owlflies...........DOMINATE!!!

Man......I almost didn't run my mercury vapor light this night.....but something told me.........

So I have had only 1 (one) single owlfly, Ululodes sp. come to my lights here in Broussard since I've been actively documenting. They're not rare or especially quirky......but I find them to be some of the most intriguing examples of the insect world.....

My very first experience with this Order was in Costa Rica, 2001. I was immediately drawn.......anyway, I still don't know much about them, but I love to photograph them......I really need to immerse myself in the ecology of this extraordinary insect!!! All photos were from 1 June 2009.

Kisatchie *BEFORE* Bugstock 6

Ok......don't get too excited..........this was supposed to be a herping trip. We (Bert Lucas, myself) failed so miserably, that I will actually post non-invert pics here.......yeah!

It was like someone walked through the entire layout & collected/demolished any living herps out there.........I mean....this is beyond "border-line embarrassing"........this is more like "Do you guys even know what yer doin'?!". Apparently NOT. As I'm spending the better part of an hour photographing what I thought was an Eastern tailed-Blue..........turned out to be a Reakirt's blue, Echinargus isola. Apparently rare in Louisiana.........shows what I know about butterflies............many thanks to Rosemary Seidler & Jeff Trahan of Shreveport for the i.d.!

Striped bark scorpions, Centruroides vittatus, (a.k.a. "stingin' lizards) are typically common under almost every place for refuge......yeah......we saw two......what the?! And so after all......remember that this was *supposed* to be a "herping" trip..................so here's a Western fence lizard, Sceloporous undulata.

Oh.......and of course, Ebony jewelwing, Calopteryx maculata, did not fail to impress.................
