Hey there,
I was walking in the woods near my house and I came across this bug. I’ve never seen a bug like this before, and I’m curious to find out what it is. A friend of mine suggested that it was a mahogany wasp, but I don’t think this is quite right because the wings are clear, it’s more of a bright red, and the bottom didn’t seem to have a stinger. I hope you’ll be able to tell me what it is, thanks!

Dear Louisa,
This is some species of Ichneumon, a member of one of the largest insect families on the planet.  Ichneumons are parasitic on other insects and arthropods.

This is an odd bug I have never seen flying around before. It looked like it was trying to drill into a stump the other day when it was noticed. If you know what this is and if it’s dangerous, an answer would be greatly appreciated.

Stump Stabber

Stump Stabber

Dear Aly,
Your inquiry is perfectly timed since we have just posted an image of two males Stump Stabbers which we believe are awaiting the emergence of a female.  This is a Stump Stabber, a female Giant Ichneumon in the genus
Megarhyssa and she is laying eggs.  The eggs will hatch into larvae that feed on the wood boring larvae of Wood Wasps, like the Pigeon Horntail.  Stump Stabbers are beneficial and not considered dangerous.  They are not aggressive and we have never heard of anyone being pierced by the impressive ovipositor, which can be as long as five inches.  It is designed to lay eggs, not to sting.

Male Stump Stabbers await emergence of female

Male Stump Stabbers await emergence of female

Dear Bob,
What a wonderful image you have provided.  These are male Giant Ichneumons in the genus
Megarhyssa, and females of the genus are commonly called Stump Stabbers because of the way they use a lengthy ovipositor, sometimes as long as five inches, to lay eggs beneath the surface of dead or dying trees or branches.  That wood is infested with the wood boring larvae of Wood Wasps like the Pigeon Horntail, and the larval Ichneumons feed on the larval Wood Wasps.  We believe these males are awaiting the emergence of a virgin female who has begun to release pheromones as she makes her way back to the surface so that they can mate.

Tarantula Hawk???

Tarantula Hawk???

Dear Don’t really care,
We thought this resembled a Tarantula Hawk, but we couldn’t figure out why it was sighted in the UK, so we contacted Eric Eaton.  His reply is posted below.  Can you provide any additional details regarding the sighting?  Did your friend recently receive any packages from abroad?

Eric Eaton’s Response
Definitely a pompilid (spider wasp), and it looks like Hemipepsis or Pepsis.  I’d be curious to know the circumstances under which it was found.  It is probably a stowaway in a shipment from the southwest U.S. or Central or South America.

European Hornet

European Hornet

Hi John,
This is a European Hornet,
Vespa crabro, and we believe this is a queen gathering wood pulp for her nest.  Soon, when her first generation of workers are able to leave the nest, she will remain in the nest and produce more eggs.  We found a fascinating website called Hornets: Gentle Giants that you might enjoy reading.

Hi Bugman!
I live in Boquete, Panama and found this nest in the tree outside my house. I know that insects are fun and interesting, but the sight of this nest gives me the creeps. Can you tell me what kind of creature builds such a nest and feels that they can hang out by my porch like they own the place?

Hi Cate,
This appears to be a Hornet Nest, but we cannot make out individual insects well enough in your image to provide an exact identification.
