Hi bugman,
As I’ve been traveling around the US for the past year, I’ve been able to identify quite a lot of my “new roommates” through your great web resource here. (Thanks!) It’s been a fun and comforting challenge to observe, document, and identify each diverse creature that I’ve come across. Currently, I’m in the Virgin Islands (so, although it is winter season, the temperatures still range from about 74-84 degrees right now). This little guy appears to be a thread-waisted wasp to me, but just wanted to seek your expert opinion.
I’m new to the area, but I’ve seen a few of them in my apartment over the past couple days, and I definitely didn’t think it was a wasp at first just because they are a much smaller size than I usually associate with wasps. I also have quite a funny group of case-bearing cloth larva living here as well, and I see the signs of termites here, but have yet to spot any individual termites. So, there are lots of friends! :)

Ensign Wasp

Ensign Wasp

Hi Rachel,
This Ensign Wasp really is your friend.  The female Ensign Wasp lays her eggs on the ootheca or egg case of a Cockroach, and the larval wasp eats the eggs and developing nymphs of the Cockroach, helping to control the Cockroach populations in homes.  The abdomen of the Ensign Wasp bobs up and down as it moves about, much like the action of signalling with a flag, hence the common name.

Daniel, thank you! Very nice news to hear about the ensign wasp helping to control the cockroach population. I appreciate your help in identifying it! :) Have a great February!
Rachel

Quite common in this area along dirt roads.
A friend’s daughter crash her car thinking the insect would sting her.

Braconid Wasp

Braconid Wasp

Hi Ken,
We agree that this is a Braconid Wasp, but it is not the same as the White Flank Orange Braconid,
Callibracon species, that is pictured on the Brisbane Insect Website.  There are many Australian Braconids with this same general color pattern.  We are sorry to hear about your friend’s daughter’s car crash, but it wouldn’t be the first time the irrational fear of an insect in the car has caused an accident.

This seems to match a photo of Therion morio.
Thoughts?

Ichneumon: Therion morio

Hi James,
You are correct.  This magnificent Ichneumon is
Therion morio.  According to BugGuide, the female parasitizes moth caterpillars, including the Fall Webworm.

Flightless Ichneumon

Flightless Ichneumon

Dear M,
We believe this is a flightless Ichneumon in the genus
Gelis.  Ichneumons are parasitic wasps that prey on a variety of insects and arthropods, though many Ichneumons are host specific.

Hello,
I found this in our backyard and was wondering exactly what it is and is it dangerous. We live in Adelaide, South Australia. Thanks.

Ichneumon

Ichneumon

Hi Jacob,
This is some species of Ichneumon, a large and diverse group of parasitoid wasps that are not considered dangerous to humans.  The female uses her ovipositor, which is visible in your photo, to deposit her eggs, often directly into the body of the host insect or arthropod.  Most Ichneumons are very host specific, and the prey include many different orders, including butterflies and moths, true bugs and other wasps.  We hope to eventually determine a species identification for this unusual Ichneumon.

Parasitic Wasps

Parasitic Wasps

Dear Ms. Mawada Saad,
If they were found in Buprestid eggs, they must be very tiny.  These are many parasitic wasps and the taxonomy of North American species it not very well organized or understood.  We suspect there must be even less documentation on species from Sudan.  We are providing a link to BugGuide so that you can compare your specimens to the images to see if you are able to at least determine a family.  We do not have the training necessary to provide any dependable taxonomy.
