I really tried to identify the 3 bugs on the snow I sent 12/1/10. At least I went thru your website and bugguide… I’m thinking you haven’t had much luck either. The one looks like a mini cranefly to me and I thought the other 2 were springtails, but they were solitary critters, and they are all wrong anyway! Any website suggestions I might peruse further? I can’t believe how addicted to bugs I’ve become since I found your website looking for an aquatic larvae! Never found the exact one, but I’m pretty sure it was some kind of beetle. Love your site and thanks for doing so much so well.

Amazing what is out on the snow, and so very tiny and frail! I found 3 different kinds today. It’s about 32F now, and last week it was -12F. I think this one is a type of springtail, but had no luck with the other 2. I left them for you to crop as I feared loss of whatever resolution there is.

Sorry, couldn’t find her, she’s about 2mm long. Why do I think she’s a she? I’ts 32F here and was -12F last week. Do I have no more sense than a bug? Actually, we both must love it here! And I know if this bug knew about your site it would love it as much as I do and be in awe of all you do. Thank you everyone that helps.

I’m just guessing here, maybe a type of springtail? only 2mm or so. Who would believe something this small at 32F and last week it was -12F. Where do the eggs/larvae/babies hang out until it gets warm(!) enough to come out and play? I saw 3 differnt kinds today. I am constantly amazed, both at the world around me and what y’all do out of the goodness of your hearts and the love of bugs.

Snow Scorpionfly in the genus Bores

Dear Cathy,
We apologize profusely.  We wrote you back the day after you sent the three snow insects and we indicated we would research you insects and post them.  We forgot.  It is the end of the semester and work is piling up and we failed to deliver.  We can tell you that none of your insects are Springtails, be we still need to research them.  The one you believe to be a Crane Fly is some species of fly, and we believe it may be a Gnat.   At least we have posted your photos and as we research, we would gladly welcome any input our readership may provide.  You might want to post a comment to the posting and you will be notified in the future if any experts are able to provide any information.

Update and Correction: Snow Scorpionfly perhaps
Hi again Cathy,
We believe the insect with the ovipositor may be a Snow Scorpionfly in the genus
Boreus.  You can check the Crane Flies of Pennsylvania website to compare the image of a female posted there.  BugGuide also has information on the Snow Scorpionflies in the genus Boreus including this description:  “Adults dark-colored with an elongated rostrum (“beak”), long antennae, vestigial wings, and long hind legs adapted to jumping; female has a straight ovipositor about the same length as the rostrum, and tapering to a point; males have a blunt rounded abdominal tip“.

Good morning Daniel,
The two wingless images are not crane flies instead, they are Snow Scorpionflies in the genus Boreus, family Boreidae and order Mecoptera   I provided some short comparison in the crane fly website here for your informaiton   http://iz.carnegiemnh.org/cranefly/limoniinae.htm#Chionea
The fly with wings is a Fungus Gnat in the family Mycetophillidae.
Have a happy and safe holiday season.
Chen

Update
December 12, 2010
I had just come to the same conclusion about the scorpionflies, thanks to your recommended website. I wish I had had my camera today because I got to see the forked projections on the backside of the male, they can raise and fold them back down flat, and he has a sort of single “Mercury wing” coming off the back of his head. Thank you and Chen so much for your help.  Daniel, you certainly don’t need to apologize to me for being busy and forgetting a few things! Thank you again.

Update:  Fungus Gnats can survive subzero conditions.

On 12/1/10 I asked you to identify what turned out to be a fungus gnat and male and female scorpion fly. I looked up the scorpionfly fly right away, probably because of the name… and found the heat of your hand can kill them! Well, I just looked up fungus gnat, and I don’t know if the one I read about is my exactr same one, but this tiny delicate thing can go to -60 and the abdomen freezes, but not the head! It will survive to -100. Here’s the website,http://alaskareport.com/news39/x71236_fungus_gnats.htm I’ve always liked bugs, but you and all your contributors have given me a new fascination for all of it! Thank you so very much.“
