Subject:  Agressive towards honeybees

Your letter to the bugman:  In my aunts garden the statchys is blooming. There are so many different pollinators, including many honeybees. This insect caught our eye. It hovers, has drone-like flight. It is visiting the flowers but it is very attentive to the competitors. It’s spends about as much time attacking honeybees as it does visiting flowers. When it attacks it seems like it bites. We see many honeybees on the ground with half of a wing, in apparent suffering- It seems they have been hurt or intoxicated

Woolcarder Bee

Dear Mollyanne,
This is a male, non-native Woolcarder Bee, a species native to Europe but present in North America since the mid 1960s.  According to BugGuide:  “Males defend their territory very aggressively not only against other males but also against other flower visitors” which explains the behavior towards Honey Bees that you witnessed.

Your letter to the bugman:  Hello,
I have two of these beauties flying around our garden, one male one female as they have been trying to mate the last couple of days.
Does anyone recognise them? I’ve lived in Spain 15 years and never seen them here before.
They are lovely.
Thank you

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.
