01/10/2010 Walking through the woods I found a large Lactarius vellereus (Fungi) in cap had a small amount of water

Lactarius vellereus (Fr.) Fr.


What I found in the water - was for me surprised. In this small ecosystem lives many small flies and their larvae.


First larvae
1.

I absolutely like this kind of contributions. Nice photo's. A pity I am not able with the identification of the diptera.

Your adult 2 is Orthocladiinae. I don't know if it is the adult of your Gymnometriocnemus larva. See also Smittia, which has strongly curved Cu2 and is found in terrestrial habitats. Metriocnemus is common in tree holes in Europe.

I don't think Sciaridae have the thoracic horns of your pupa 5. I can't figure out where the antennae are, or the details of the tip of the abdomen. Straight legs extended well past wing tip rule out several families.

So many pictures for identification in one thread is rather confusing... And that number 5 probably is a dolichopodid.

Penultimate picture is Superfamily Chalcidoidea (Hymenoptera) maybe Trichogrammatidae or Aphelinidae, I think last photo is Hymenoptera too, but it's not clearly for me..

Hi Paul
Yes .... this thread is rather confusing... :o but I give it not for ID but for interest...
(and I wanted it to be together)
and thanks for dolichopodid
Jozef

Thank you for your insight and ID
I'm studying Tree holes in Slovakia and Metriocnemus is relatively frequent in each tree which I deal ... but sometimes I find Gymnometriocnemus too but in small quantities

Dear Jozef
Photo 6 looks like Limonia (Limoniidae) and I was wondering If you could spare me this Oligochaeta on photo 10. It is immature for I cannot see any clitellum, but it is a very peculiar habitat and as I'm in the process of writing a guide for the oligochaeta I would be very interested in this specimen.
(you have my mail)

Penultimate is Eulophidae, the last is Diapriidae.

Jozef:

Unknown 3. is a female specimen of Rondaniella dimidiata (Mycetophilidae),
Unknown 6. is a male specimen of "Black-winged Fungus Gnat" (Sciaridae),
Unknown 7. is a female specimen of Gall Midges (Cecidomyiidae) and
other fly numbers (1., 2., 4. & 5.) are correct assigned to family.


so long,
xylo

Dear Paul
Are they both female?
Thanks a lot
