Identification of Hymenoptera (wasps, bees, ants)

S. angustatus has rounded shoulder angles. I think it's S. bifasciatus (=mutiensis, =sinuatus). It doesn't differ much from the ones I have. even in terms of color.

something from Megastigmus, I have similar rose hips came out, the whole windowsill was strewn. I think Megastigmus aculeatus is called

Ant lovers, help! Crimea, Simferopol, December 2013, indoor. I did not collect it, but those who collected it say that these things sting painfully, but they brought me only males (2 pcs.). Body length is about 4 mm, middle shin with two spurs. Cryptopone ochracea?

Hello everyone Please tell me where you can view information about the biology and ecology of this ant - Cataglyphis aenescens (Hymenoptera, Formicidae)? Do you have scans of the works themselves? Thank you very much in advance!

Bumblebee looks like B.

Yes, I know that these are ants, there can be nothing else by the venation of the wings and the number of segments of the antennae. There were (no longer any) doubts about the subfamily.
And the collection of sexual stages will probably be more interesting for a forum participant named TimK.

Can you help me with the wasp? MO, July, 10 mm

Someone from the Eumenidae?

Good evening, I ask everyone who knows to help with the definition. We were in Taba (first half of October 2013), in Egypt, on vacation. I also met a fairly large ant (about 1 cm):

Dolichoderus quadripunctatus (Linnaeus, 1771)

Ant of the genus Camponotus. I'm not good at foreign sports.

I agree with your version, thank you for the hint! I think I also found the specific name Camponotus maculatus (from the post on the page:

http://www.lasius.narod.ru/antShev03.htm )

Unfortunately, it's not all that simple. There are several similar types, the differences of which I do not know exactly and which may be there. For example, it can also be Camponotus fellah or Camponotus sanctus. And his fool knows who else might be there.

Strange version. Not only is it not at all similar, so Dolichorerus (hard workers) will not pull more than 6 mm.

It's clear. that taxonomy is not a simple matter and is very confusing. But in Camponotus fellah and Camponotus sanctus, the color of the abdomen is clearly striated, and not spots like in Camponotus maculatus. Or such a broad reaction rate?

Can I define up to the view?
