Your letter to the bugman:  Dear Bugman,
My sons and I were on a Father/Son retreat and we discovered this pinkish caterpillar w/ one long black strip down its back from its head to its rear-end.  It also had several black stripes that ran perpendicular to its one long black stripe.  The total caterpillar length was roughly 1 and 3/4 inch in length.  We know that their are likely many undiscovered insects and maybe caterpillars.  We’re wondering if the caterpillar we discovered on a small tree branch is already identified as we could not find it when searching for caterpillars in MN.  The photo attached is in my Sons terrarium and the red mushroom looking thing next to it is only a decoration.  We didn’t want to touch the caterpillar for a better picture for fear of a sting, or rash.

Elm Sawfly Larva

Dear Richard,
Thanks for clarifying the identity of that red decoration with the spots.  As we were formatting the image and color correcting it for posting, we obsessed on its identity.  This is not a caterpillar.  We suspected it to be a Sawfly Larva, but the markings are unusual, but our internet search produced several images that confirm our suspicions that this is the larva of an Elm Sawfly.  We have received images in the past of Elm Sawfly larvae that are yellow, green or pink, and they have a black stripe running the length of the body on the dorsal surface, but those traverse stripes are unusual.  There is a small image on the Wisconsin Department of Natural Resources website with a caption that indicates “Elm sawfly larvae are typically yellow; it is uncommon to find the pink form” but it does not mention the traverse stripes.  Additional images on Insects Galore and Forestry Images also document these unusual markings.  The adult Elm Sawfly is a non-stinging relative of wasps and bees.  Elm Sawfly larvae will not sting and they will not produce a rash.

Ground Beetle Larva

Dear Cher Mom,
Immature insects often present greater identification challenges than adult insects present.  We suspected this to be a Ground Beetle larva and we found supporting visual validation on Project Noah which has a similar looking image identified as a Pterostichini sp. and on BugGuide where a similar image is identified as a
Pasimachus species.   Ground Beetles are predators as larvae and adults and Caterpillars are often a preferred prey.

Your letter to the bugman:  This odd creature flew into my phone, bounced off & landed in front of me. It then proceeds to waggle it’s purplish wings & tasseled abdomen at me before retracting it’s wings (somewhere!) Only to produce them once again & promptly take off. It’s a hot and steamy August here in Virginia. I’ve been a keen observer of nature all of my life & can honestly say, this one has stumped me completely. Hope you guys can help me out!

Rove Beetle

Dear Holly,
You have good reason for being stumped.  This is a Rove Beetle in the family Staphylinidae, and many members of the family look very different from the “typical” beetle.  Unfortunately, BugGuide is currently experiencing technical difficulty and we cannot search for the species, but luckily, we were able to identify it as 
Platydracus maculosus in Beetles of Eastern North America by Arthur V. Evans where it states it is:  “the largest rove beetle in North America.”  The image with its abdomen curled up is a typical threat posture for many Rove Beetles.

Your letter to the bugman:  I’ve just noticed these in my yard this year – and there’s quite a few of them.   Yesterday I saw one holding another smaller bug (gnat maybe?)in its, so I’m thinking they might be carnivorous.

Gnat Ogre

Dear Frankie,
Your submission has us terribly amused.  We immediately suspected this to be a predatory Robber Fly in the family Asilidae, and we tried a web search for Robber Flies with huge eyes, and we quickly found some images posted to BugGuide indicating it might be in the genus
Holcocephala, but alas BugGuide is currently having technical difficulties and is not available, so we searched that genus name elsewhere and we encountered Discover Life where we learned members of this genus are commonly called Gnat Ogres, hence the source of our amusement.  For the sake of continuity, we are going to assume the prey you witnessed was in fact a Gnat.  The name Gnat Ogre is also used on iNaturalist.  According to iNaturalist, there are 40 species in the genus.

Thank you! I love the name!!!

Stump Stabber

Dear Gillian,
This is a female Giant Ichneumon in the genus
Megarhyssa, probably Megarhyssa macrurus.  Giant Ichneumons are sometimes called Stump Stabbers because the female uses her long ovipositor to deposit eggs beneath the bark of trees infested with wood boring larvae of Horntails.  They are not aggressive and they do not sting.

String That Moves

Dear Debbie,
We prefer not to weigh in on the state of your mind, but this looks to us to be a string that moved.  The object on the end of the toothpick appears to be of fibrous nature, possible plant or animal fibers, though we would not rule out it might be synthetic.  Light weight fibers will stir with the slightest breeze.
