Subject: Is it, could it be… a “Fairy Fly” wasp?

Olá WTB?,
I was on the laptop the other night, even looking at WTB when I saw a tiny, tiny bug on the screen, grabbed the camera and took some photos. The bug was very accommodating, apparently quite interested in the light from the computer screen. Finally though I encourage a transfer onto a paper receipt so I could hopefully get some better pics not in a backlit. But, still the tiny bug stretched the limits of my little camera.
It would seem the bug is at least a tiny wasp, but… is it possibly a fairy fly wasp? S/he seems to have long enough antennae and be small enough (that’s my middle finger in one of the photos and I have small hands). The receipt shows numbers on the other side that only measured about 1mm so that’s the size of the little flyer too.
Still February in Porto but the bugs are not waiting.
Thanks again for all you do. :)

Dear Curious Girl,
We are posting your photos, and we hope some eminent expert on Parasitic Hymenopterans can provide you with a conclusive identification, but that is beyond the scope of our ability.  We believe this is some type of Parasitic Wasp, and you can view a wealth of species from North America on BugGuide.   At last, we are getting some rain in Los Angeles, but the experts warn that this is not a sign that the drought has ended as the snow pack is still well below average.  This rain will doubtless result in a fabulous display of desert wildflowers in the coming weeks.

Cool Daniel.
Do you think it could be Aphidiinae Braconidae (Braconid Wasp)?
Apparently they are part of Integrated Pest Management against aphids (and they get really convoluted when they attack). Funny as I did get a picture of an aphid just outside too that day though I wasn’t trying to get that one.
Here’s a couple bonus pics (though the “bug” doesn’t look much different in them). Hope you find them cool.
Plus, even though I know it messes with your system I’m sending a couple of a different tiny wasp from London’s Hyde Park last September because it came up in my search and they are so similar plus I just realized the victim for this wasp might be on the flower too! You think? I don’t believe I knew either were there when I took the picture. I think I was just trying to get the flower and the bonus was bugs.
Very cool on finally getting some rain, and hopefully some great flowers (take pictures!). I was in Death Valley once when it rained and it seemed almost immediately a bajillion tiny, tiny flowers carpeted the desert. As you no doubt know, lack of rain has not been a problem in this part of the world (especially the UK). When I was there in March ’12 they were thinking there might be a drought, so implemented water conservation only to have the 3rd wettest summer ever (which of course I also was able to experience… ::sigh::).

Hi again Curious Girl,
We couldn’t resist posting your new photo in a shameless bit of self promotion.  We are also including your London image with the same posting, discarding all efforts at “neat” categorizations.  It has been pouring all night in Los Angeles, and we are expecting the rain to stay with us for over 24 hours.  It is a perfect day to stay home by the fire, but alas, we must soon drive to “the valley” for work.  We are not looking forward to the hectic morning commute.

Hi,
Live in Ghana, west Africa, these bugs keep appearing in my bedroom, never seen them before anywhere else. I’ve lived in the US before and never saw them there either. My biggest concern is if it is harmful, like carry some disease. Please help! Thanks

Dear ND,
This is a Wasp, not a Fly, and it does not carry disease.  We are surmising that once we tell you that this is a beneficial Ensign Wasp that parasitizes the ootheca or egg cases of Cockroaches, helping to reduce their populations, that no additional individuals will fall victim to Unnecessary Carnage.

Dear Daniel,
I really appreciate the information and advice, especially knowing how much you have to work on each day.
I also want to assure you that these wasps will no longer suffer at my hands.
Best Regards
Nukunu

Hi Tara,
We believe this is a Crane Fly in the family Tipulidae.  There are some images on the Brisbane Insect site that look similar.

Hi,
on Feb. Feb.20, 2014 “Tara” posted an isect from New South Wales, Australia.  You answered that this might be a crane fly / Tipulidae, but if you look at the wing venation it is evident that this insect does not belong to the Diptera at all, it’s Hymenoptera. It’ another parasitic Hymenoptera, Ichneumonidae or Braconidae. You may compare the wing venation of a Tipulidae here: http://www.metafysica.nl/nature/insect/hennig1954_7.jpg

Thanks Erwin.  Because of an earlier comment, we have already addressed this error, and we will add your comment to the posting.

my son was eating lunch when I noticed this little beauty on my table! It is about 1 inch long, tip of antenna to end of abdomen. Six legs, two sets of wings. So beautiful! I have never seen these in my area before!

Ichneumon

Hi BB,
This parasitic Ichneumon Wasp is in the subfamily Ophioninae and you may read more about them on BugGuide.  This is one group that is frequently attracted to lights, and though we generally inform our readers that Ichneumons are harmless, we learned several years ago that this group is known to sting.  According to BugGuide:  “Females have a very compressed abdomen and a short, very sharp ovipositor. The ovipositor can penetrate the human skin; most other ichneumons can’t ‘sting’.”

Hi Bugman,
I found this cool little Fairy Fly while going through a trap sample today at work, and I took the opportunity to take a size comparison photo with a grain of sand. I noticed that there aren’t many Fairy Fly photos up on What’s That Bug, so I thought I’d submit the little guy.

Fairy Fly

Hi Brian,
Thanks so much for sending us your photo of a Fairy Fly, the common name for a Parasitic Hymenopteran in the family Mymaridae which are classified with the Chalcid Wasps.  As you indicated, we only have a single, very old image of a Fairy Fly in our archives.
  According to BugGuide, Fairy Flies parasitize the eggs of other insects and they are:  “Fairly characteristic in habitus and do not closely resemble any other chalcidoids. The most easily observable characters are(2):
stalked, narrowly elongate hindwing
long clubbed female antennae (filiform in males)
greatly reduced venation which terminates within the first third of the wing (except in Arescon and Krokella)
no discernible stigmal or postmarginal vein
tarsi may be 4- or 5-segmented
antennal toruli widely separated
vertex surrounded by thickened bands of cuticle and separated from the face by a suture.”
While we don’t fully understand all of that, we are providing the information for our readers.

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

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
