I found these ants outside my back door on the bricks. This colony poped up over night.

Wheel Bug Hatchlings

Dear Joe,
We corrected what we perceived to be an overwhelming cyan cast to your photo and it accentuated the red in the abdomens of these newly hatched Wheel Bugs. You can still see their empty egg mass in the lower left quadrant. We will be flying into Pittsburgh in two weeks.

Wolf Spider with Egg Sac

Dear Frog,
Thank you for your photo. We often get photos of female Wolf Spiders covered with spiderlings, but we don’t have many photos of them with their egg sacs. The female Wolf Spider cares for her eggs and hatclings until they begin to disperse.

Spider Egg Case

Subject: Unidentified, Unusual Egg Case

Dear Bugman:
I found this unusual looking egg case, while hunting for fossils. It was in a crumbly, sedimentary boulder, along with dozens of sow bugs, which were exposed when I split the rock open. The eggs are visible as round bumps through the papery/silky covering. Was wondering if some type of spider made this, or another kind of arthropod such as the sow bugs?

What’s That with the Sow Bugs??? A Spider Egg Case.

Dear Chris,
We do not recognize this thing, but we would not rule out a fungus. We are posting this as unidentified and we hope that either we or our readership might find and answer for you.

Dear Daniel: After looking all over the internet for similar photos & an answer, I found a link on Bug Guide which has an almost identical photo of this type of egg sac. It appears to be the creation of a type of ground spider. Species mentioned during my searching are gnaphosid, zelotes and corrinidae. Here’s a link to the pic on Bug Guide: http://bugguide.net/node/view/181688/bgpage

Dear Chris,
Thanks so much for following up on this posting.

Owl Butterfly Caterpillar with Tachinid Fly Eggs from Costa Rica

This is a little friend I found deep in the Jungle in Costa Rica. Anyone who what he is?

What’s That Caterpillar???

Dear Ryno,
We do not recognize this unusual looking caterpillar. Generally Butterfly Caterpillars are not hairy, but we suspect this might be a Nymphalid Caterpillar.

Keith Wolfe responds to our identification request
Greetings “Ryno” and Daniel, this is a last-instar Caligo atreus (http://janzen.sas.upenn.edu/caterpillars/dblinks/searchplaycat4.lasso?-Search=GCAcaterpillars337&herbivore%20species=atreus). Note the numerous white tachinid (http://www.nadsdiptera.org/Tach/Gen/tachintr.htm) eggs behind the head capsule, the inevitable doom of which it might possibly escape if pupation occurs before the maggots hatch.
Best wishes,
Keith

Hi Keith,
Thanks for getting back to us on this. We didn’t realize those were Tachinid Fly eggs. Good to know. We hope this Owl Butterfly Caterpillar escapes being eaten alive by the fly larvae.

Giant Stonefly with Eggs from Canada

hi bugman!
This colourful flying insect had a collision with my brother’s mower. I think it’s a Stonefly. The closest match I’ve been able to find is Utaperla gaspesiana.
The eggbundle was attached to the insects abdomen.

Giant Stonefly with Eggs

Dear Storm,
While we agree that this is a Stonefly, we disagree with your species identification. While the markings on Utaperla gaspesiana as pictured on BugGuide look similar to the markings on your individual, we believe you have a Giant Stonefly in the genus Pteronarcys. We were most curious about the egg bundle, so we did some research. We located a similar photo on FlickR with the comment: “Found this on a screen door, perhaps 100 yards from a brook. Large (2″?) egg-laden female. I think it may be Pteronarcys dorsata. May 28, 2011.” The photographers, Jerry Schoen took the image in White Oaks, Williamstown, Massachusetts. That same photo can be found duplicated on numerous other websites including The River’s Calendar. The Elk River Guiding Company website also has a photo of a Stonefly with Eggs. You can read more about Giant Stoneflies on BugGuide.

Kudzu Bug Laying Eggs

We have a large abundance of these small ladybug sized bugs in our yard. They came out about 10 days ago and there are 100’s in our yard. Areas appear black or dotted there are so many of them. One photo is a close-up of the bug, the other is how they are scattered on the house. Can you help identify and provide some information?

Kudzu Bug lays eggs

This is a Bean Plataspid or Globular Stink Bug, Megacopta cribraria, which is also called a Lablab Bug. We don’t know the origin of the name Lablab Bug, but we are amused by it and that is our common name of choice for this Invasive Exotic Species. We first received a report from Georgia in 2011 of this species and learned that it was first discovered in North America in 2009. Since that time it has spread through the south. It feeds on another invasive species, the Kudzu, and according to BugGuide, which is now using Kudzu Bug as the common name of choice, it is: “the only member of its family reported from the Western Hemisphere.” BugGuide also notes: “may invade homes in large numbers and become a household pest; highly invasive species of mixed impact: it seems to prefer kudzu (a highly invasive and damaging plant), but can also become a serious pest of leguminous crops.” We have received numerous reports of Home Invasions.

You stated you were amused by the name LabLab. I occasionally grow a beautiful asian bean that goes by the name of hyacinth bean or LabLab. I would strongly suspect this is the origin of the nickname. By the way- LabLab is particularly striking when grown together with blue Morning Glories here in Chicago. Love your site and always will even if my contributions never find their way to the web page! Your Always Faithful Reader, Ted

Thanks for the informative comment. We are troubled to learn that you have submitted identification requests or other potential website content and we haven’t ever posted anything. Much of the selection process is luck, but a catchy subject line generally gets our attention as well.

Polyphemus Moth Ovipositing

Can you please identify this specimen? I am presume it is a moth based on the ’fuzzy’ antenna.

Polyphemus Moth

Dear Danno,
This lovely moth is the widest ranging North American Giant Silkmoth, the Polyphemus Moth. It is wonderful that one of your images has captured this female in the process of ovipositing. Hopefully she had a chance to mate. Giant Silkmoths do not feed as adults, and they only live long enough to mate and produce a new generation. The male Polyphemus Moth has more feathered antennae so that he can locate the female by the pheromones she releases.

These ?eggs were found adherent to a small branch of a baby apricot tree. What are they and will they harm the tree?

Katydid Eggs

Dear concerned gardener,
Do not be concerned. These are Katydid Eggs. You can verify that by looking at the images on the Missouri Botanical Garden website where it states: “They do not pose any particular problem for the home gardener, but do feed on shrub and tree foliage.” We welcome Katydids to our own Mount Washington, Los Angeles gardens. Though they eat leaves, we do not consider them to be a problem and we like seeing and hearing them. Many Katydids including Bush Katydids resemble green grasshoppers with really long antennae.

Thanks!!! You are awesome!
