Your letter to the bugman:  I have found a bug in my aquarium with fishes. It was flat bug that looked even like it was made of plastic. Is it possible that it was growing in the aquarium?

Drowned Western Conifer Seed Bug

Dear Edie,
This is an invasive Western Conifer Seed Bug and it did not grow in your aquarium.  It must have fallen in and drowned.  This North American species, which is pictured on BugGuide, is invasive in Europe.

Your letter to the bugman:  I’m the go-to bug identification nerd for friends and family; if I don’t know them outright, I can almost always track them down on What’s That Bug. This one, though, evades me. Any chance you can help out? this is the only photo  they got. Thanks very much.

Diaprepes Root Weevil

Dear Mike,
This is an invasive Diaprepes Root Weevil,
Diaprepes abbreviatus, and according to the Statewide Integrated Pest Management Program:  “The diaprepes root weevil damages both the leaves and the roots of plants. The adult weevils damage leaves by chewing semi-circular areas out of the leaf margin. There may also be frass or weevil droppings near the areas that have been fed upon. The grub-like larva feeds on the roots of a plant, weakening or killing a plant.”  According to the Center for Invasive Species Research:  “This pest has a very wide host range, attacking more than 270 species of plants in 59 plant families.  In Florida citrus groves, Diaprepes root damage allows, Phytophthora, a very serious and often lethal plant pathogen to invade roots further hastening the decline of trees.”

Introduced Pine Sawfly Larva

Dear Lori,
We thought this was going to be an easy identification, but more than an hour later, we can state unequivocally that we were way wrong.  Our mistake began by not looking at your image that closely, and thinking we were trying to identify one of the Hooded Owlet Caterpillars in the genus
Cuculia, but after ponderously searching BugGuide, we realized we were wrong.  Our search next took us to The Moth Photographers Group where the Zebra Caterpillar looks similar, but not the same, and the Scribbled Sallow Moth Caterpillar pictured on The Moth Photographers Group and the Toadflax Brocade Moth Caterpillar, also pictured on The Moth Photographers Group also looked similar but not the same.  The solid black head on your individual and the round yellow lateral spots were quite distinctive and not found on any caterpillars we could locate.  Something about the head did not seem right, so we decided to count prolegs, and there appear to be seven pairs, which caused us to think this must be a Sawfly larva.  According to ThoughtCo: “Caterpillars may have up to five pairs of abdominal prolegs (tiny limbs) but never have more than five pairs. Sawfly larvae will have six or more pairs of abdominal prolegs.”   Once we searched for Sawfly larvae, we came to Wildlife Insight where we found images that match your individual that are identified as Diprion similis.  Armed with that information, we returned to BugGuide and located matching images of the Introduced Pine Sawfly larva, but the individual in your image does not appear to be eating pine.  Upon what plant did you find it?  According to BugGuide:  “hosts: pines (Pinus); 5-needled pines (Subg. Strobus) are preferred, but others may be infested as well.”  This BugGuide image contains the information:  “This one was on a poplar plant, and the other was eating oak leaves.”  Thank you for submitting this challenging identification request.

This was feeding on Cosmos. Glad it was a challenge as many friends including the Exec director of Audubon here in CT. could not ID.

Your letter to the bugman:  greetings Bugman.  I have found your site randomly but joyfully.  are you the Bugman of whom Albuquerque Speaks such praises ?    my daughter recently moved to ABQ.  I saw your work on a documentary, I believe & encouraged her to offer herself to volunteer as she is an avid entomologist .. with a background in pathology.  now, the accompanying image is of a foamy pod adhering to a dried plant stalk in swampland near NOLA.  a friend asks & I am curious as well.  thanks to you, for this great site… you are generous and the education opportunities your offer the seeking here on social media reaffirms my faith in humanity, yes indeed.

Egg Mass of Apple Snail

Dear Rebekah,
Thanks so much for your fervid praise, but we don’t know anything about Albuquerque Speaks.  We did feel compelled to get you a proper identification and we believe we have properly identified this as the Egg Mass of an Apple Snail in the genus 
Pomacea, and there are several invasive species. According to Featured Creatures:  “You can scrape off the egg masses and allow them to fall into the water since inundated eggs will not hatch. However, only pink egg masses should be scraped or removed. Egg masses with large, white eggs were laid by the native Florida applesnail and should be left undisturbed, as they do not pose a threat and are the principal food of the Everglades kite. Never release applesnails from aquaria into the wild (FFWCC 2006).”  ResearchGate also has an image of a pink Apple Snail Egg Mass.
