Hello there! I am an insect person who loves insects and is hoping to maybe become an entomologist one day. I have many insect pictures which I am trying to identify. I also have a collection of insects I find every now and then dead on the ground. (I don’t kill bugs for my collection, I only take them if they are dead). I do however have many I cannot identify. I have tried my 5 insect guides, google search, many bug identification guides online, and google image search but have came up empty handed. One of which I have failed to identify is this blue fly I found in the everglades. It was taken with a Sony-cyber shot camera. So I was wondering if you could help identify this insect. Thank you!

Dear Cicada Lover,
This gorgeous creature is not a fly.  It is a Cuckoo Wasp in the family Chrysididae and probably in the Subfamily Chrysidinae which is pictured on BugGuide.  We are very fascinated with your “dead insect” collection philosophy.

Abdomen and thorax colouring of Chrysidid wasp, head of a fly?
Any help with ID would be greatly appreciated.

Dear Stevie,
We believe the similarity to the head of a fly in your image is an illusion, and that your Cuckoo Wasp is
Chrysis ignita which is pictured on BWARS where it states the species is found:  “Throughout England,Wales, Scotland and Ireland but not found on the Orkney and Shetland Islands. Recorded from the Isle of Man, Isle of Wight, the Isles of Scilly and the Channel Islands.”

Dear Tineke,
This looks like a Cuckoo Wasp to us, but the red abdomen is something we do not see in North America.  It might be
 Hedychrum rutilans which is pictured on Shutterstock.  There is also some information on Chrysis.net.  Cuckoo Wasps can curl up for protection when disturbed or threatened as your image indicates.

Thank you very much Daniel for your quick respons…
Its a beautiful insect, it was dead when I found it and I keep it in a little box.
Best regards,
Tineke

Subject: Metallic Blue Bee?

I saw this bee (?) in my yard here in northeast FL. It was a striking metallic blue, with some green especially on the underside of the abdomen. Size was about 1 1/2 to 2 cm. I thought it might be a sweat bee that was more blue than the green I usually see. But it looks like the bee might be eating something, maybe a smaller insect, which would make it something besides a sweat bee. Whatever it is, it was a beautiful blue color.

Dear Karen,
This beautiful Hymenopteran is not a bee, but rather a wasp, a Cuckoo Wasp to be exact.  Cuckoo Wasps in the family Chrysididae lay eggs in the nests of unsuspecting hosts, other Hymenopterans.

I have only seen this bug twice in 3 years, both times in the summer. Its antenna move very fast, and I found out they are extremely sensitive to vibrations. Not very good pics I know, just tell me what else you need from me to identify? He’s not aggressive at all and is actually very beautiful up front.

Dear WeirdKitty,
This is a Cuckoo Wasp in the family Chrysididae, and the common name arises, according to BugGuide, because of:  “the fact that these wasps lay eggs in the nests of unsuspecting hosts.”  Cuckoo Wasps are harmless to humans as they cannot sting.

Oh thank you very much!!
That’s pretty interesting, I will definitly be doing more research. Thank you!

Found this little beauty in our warehouse. It has a blue-green iridescent exoskeleton and flies really quickly, but not much range. I was able to catch it without much damage. As you can see, it has a wicked stinger/proboscus with an alarming extension for its size! I got a couple of close-up images while holding it with tweezers. Any ideas on identification?

Dear ISS,
This lovely wasp is a Cuckoo Wasp in the family Chrysididae, and despite its fearsome looking stinger, it is not an aggressive species and it is not known to sting humans.  According to BugGuide:  “The female sting has been modified into an egg-laying tube with highly reduced valvulae and poison gland. As a result, unlike most other aculeates, chrysidids cannot sting and can be easily handled.”
