Hi,
Is this a caterpillar?
It was about 30mm long, sitting on a Lomandra leaf.
It was in a brigalow forest , about 400m altitude.

Slug Moth Caterpillar, we believe

Dear lsbth,
We believe this is a Slug Moth Caterpillar or Cup Moth Caterpillar in the family Limacodidae, but we have not been able to locate a matching image to substantiate that belief.  This species does not appear to be pictured on the quite comprehensive Butterfly House websitePerhaps one of our readers will have more luck than we have had.

We have zillions of little worms hanging from Cobb webs out of the tree and the porches. Really everywhere. What r they and what can we do about them?

Dear Michelle,
In the past, we have gotten reports of Oak Leafroller Caterpillars,
Argyrotaenia quercifoliana, hanging from trees, but a closeup of your caterpillars indicates they are a different species in the Spanworm or Inchworm family Geometridae.  We will research this and try to come up with a species identification for you.

They are killing my trees I think and I’m not sure what to do.  Parts of my trees are brown where they were budding leaves last week

Newly Planted Apple Tree, we presume.

Hi again Michelle,
One tree image you provided appears to be a freshly planted Apple Tree.  Please provide information on the tree.  What is it?  When was it planted?  Is this the only place you are finding the caterpillars?  It is possible the eggs were on the tree when it was purchased and now that all the young leaves have been eaten, the caterpillars are on the move searching for more food.  If their diet is limited to the leaves of apple trees, they will starve and you will no longer have the caterpillars, and unless the tree is really unhealthy, new leaves will sprout.  We just noticed you also attached an image of a large tree.  What kind of tree is it?  Are the caterpillars on all of your trees or only on selected trees?  The large tree should have no trouble resprouting if it is an otherwise healthy tree.  Birds and other insectivore predators should help to keep the numbers of caterpillars in check.

This beetle was attracted to a light. It looked like a very large broad-nosed weevil to me, maybe 2 cm.

Weevil or Longicorn???

Fungus Weevil

Dear Steve,
We agree that this looks like a Weevil, though we have never seen a Weevil image with such long antennae.  That trait is more like a Longicorn in the family Cerambycidae.  We have not been able to locate any matching images from either family from Trinidad, or any other place for that matter, so we are posting this beetle without identifying it and we hope to get a second opinion, and perhaps some assistance from our readership.

Unidentified Longhorned Weevil

Longhorned Fungus Weevil

Update
Cesar Crash of Insetologia, a Brazilian site similar to our own, provided us with a link to the Paraguay Biodiversidad site of the family Anthribidae that includes an image of Ptychoderes mixtus that looks identical to the image submitted by Steve.  A similar image can be found on the Coleoptera Neotropical site.  Anthribidae are commonly called Fungus Weevils.

Eric Eaton confirms
Daniel:
This is a fungus weevil, family Anthribidae.  Males of many species have really long antennae.
Eric

Thank you for the update and thanks to Cesar Crash for pointing me toward a possible ID. The descriptions for many in this genus are in German which I don’t speak. However I did find a key to some of the species:
Karl Jordan, 1907. Biologigia Central-America. Insecta. Coleoptera 5(6): 303
http://biodiversitylibrary.org/page/583600#page/315/mode/1up
It appears that Ptychoderes mixtus is a good contender and may be in range. Ptychoderes rugicollis is also possible. Barcoding Life images show the latter with shorter antennae. There are no images of the former. So P. mixtus does seem like a reasonable tentative ID.
Best Regards,
Steve Nanz

Subject: Which fly?

Hello,
I came across this fly on the bark of a Mahogany tree.
It’s got a single pair of wings and measures about 2cms or so.
Any clues much appreciated.
Thanks & Regards,

Dear Rahul,
We do not recognize your colorful Fly, but we will post the image in the hope that one of our readers will be able to assist in the identification.

Thanks for trying Daniel!

Subject: On our burr oak, in Texas.
Location: Arlington, TX

Hi,
My partner asked me to grab a picture of this and see if I could help him identify it. He’s been seeing these on our burr oak, here in North Texas, since the leaves started budding this week. He’s says there are “lots” of them. He seems to think they have been laying eggs, but I haven’t seen what they have been up to to confirm this impression (and, obviously, he’s not really a Bug Guy).
For the record, it is late March, and the weather has been warming up here for a couple of weeks. (it’s up to the 70’s and low 80’s this coming week, already.)
I have included both the closer detail crop, adjusted for clarity, and the wider shot for some idea of size. They are small, probably… a half-inch? Maybe? Those are very early leaf buds at the end of an almost twig-like branch that this one is sitting on. (Sorry it is not more clear, it was already evening when he asked me to take the photo.)
Thanks! I hope you can help us out!

Sawfly, we believe

Sawfly

Dear Kelly,
We believe this is a Sawfly, a non-stinging relative of wasps and bees.  The theory that it might be laying eggs is valid.  The larvae of Sawflies are often confused for caterpillars, and if they are numerous, they can defoliate some plants.  We are going to continue to research this request and we are also going to try to get an opinion from Eric Eaton.
  The Ladybird Johnson Wildflower Center website mentions “oak leafmining sawfly (Profenusa lucifex)” as an insect that feeds on Burr Oak, and though we could not find the species pictured on BugGuide, members of the genus look similar.

Eric Eaton confirms Sawfly and provides possible species identification
Yes, definitely a sawfly, perhaps Pristiphora chlorea.
Do you know how to do an “advanced search” in Bugguide?  That is often how I come up with answers for you.  Don’t get me wrong, I enjoy the challenge of finding you an answer! 🙂

Subject: Bugs in Costa Rica

We saw these bugs on the side of the road in Manzanillo (Caribbean coast) in Costa Rica a few days ago (early March). I asked Tracie in Drake Bay as we did a tour with her but she said they are nymphs and without the adults around the chance of identification is slim. She told us to contact you. Any idea what they could be ? Thanks so much.

Dear Sonia,
Tracie is correct, kind of.  Nymphs are often difficult to identify conclusively, however, these nymphs are very distinctive in color and markings.  Our initial gut instinct is that they are in the family Coreidae, and that they remind us somewhat of members of the genus
Thasus.  Our initial search did not provide any visual matches.  Perhaps one of our readers will have better luck.  Cesar Crash may be able to come to our rescue on this.

Thanks so much for your quick reply, Daniel.. Please do let me know if you find out more. We thought they were very distinctive too and find it all quite exciting.
