Hi guys. Your assignment for the day, should you decide to accept it, is to take  
a gander at this bug and see if you can identify it to the (ideally) species level.  
If not species, genus will do.

[Unidentified Insect](http://www.cirrusimage.com/unidentified_arthropods.htm)

I will be forever grateful to anyone who can help me out.  
I’ve looked high and low on the web - the trouble being,  
I don’t know if this is a wasp, or a fly, or what. Thanks!

Nick

I’m guessing wasp myself. It’s really tiny, right?

Looks like a Sawlfy (Order Hymenoptera) but would need to see more detail (genitalia, tarsii, etc.) to bring it down to family and genus.

Sawfly, I mean. It is a type of wasp.

That thing sticking out the back seems way too big to be a stinger. Is it an ovipositor?

Judging by the configuration of the thorax (triangular pronotum, extending to wing joint) presence of ovipositor, lack of stinger, threadlike antennea, etc. I would say that this is a member of the Ichneumonidae family, order Hymenoptera

It might be this little[guy](http://www.discoverlife.org/nh/tx/Insecta/Hymenoptera/Ichneumonoidea/Ichneumonidae/Pimplinae/#Natural%20History) but the abdomen seems too narrow

HYMENOPTERA: ICHNEUMONIDAE

Yup. It’s one of those, I think. But I looked at dozens of them at this site: [Insects of Cedar Creek](http://www.cedarcreek.umn.edu/insects/albumframes/025frame.html)  
and I can’t seem to match it with anything. DAMMIT.

I looked at every single bug on that page and I saw nothing that I would say matches. I think the closest I can hope to get is the family name. I will leave the rest to someone with far more patience 🙂

It occurs to me that I have just spent the past hour trying to identify a bug that I will probably never ever see again in my life. It also occurs to me that it was the most interesting hour I have spent in quite sometime. I am such a geek!

Yeah, I was afraid of that. Well, thanks for your help, all.  
Maybe Cecil will take pity on a poor amateur entomologist…
