[ID] Insects, please ()!

Hi all,

Just some quick invertebrates requiring a look, thanks!

Oct/Nov 2009

About 1mm, likely less. Large insect is a Chrysomelid, Longitarsus sp - Flea Beetle.
Found hanging to invertebrates drowning in bodies of water. I only saw these when I had a Plant bug under the microscope. Look a little like Springtails, but tiny and orange

Triozidae member...
...but which? Taken inside specimen pot, about 5mm inc. wings.

Trichocerid gnat - abdomen detail and genetalia (ventral view)
It seems to have a banded abdomen... Trichocera annulata per chance?

I collected the last in a specimen pot - now invaluable! I got the second shot (of the genetalia) by chance, then later realised it could be great for ID, though ideally should be closer, under a microscope.

Thanks for looking!

Take care,

Jason

The psyllid is probably Trioza remota - everything fits, and it's one of the few common ones around at the moment, usually on conifers.

Thanks Joe - I did hope!

Did the underside shot help at all? I found it on an Ivy plant... well, a fence under it where it's overhanging.

Is the Chrysomelid dead? do you have a more clear photo? hard to say genus from this let alone species the colour seems too dark for similar species making me think this is dead.

I think you're correct with annulata.

Hi Dan, the Chrysomelid was alive, albeit near drowning. I freed it, and off it went. I'll upload other shots tomorrow (Thursday) if I have them still. Should do.

Thanks John - annulata I'm sure it is too. I remembered your banded abdomen tip

Hi Jason,
The underside shot did show the antennal colouring, which was a pretty important pointer, so certainly worth having!

Excellent. As for the side shot, I should have taken that 'In the field' as opposed to through plastic

A specimen jar... pretty under-rated maybe - by me until now, anyway! Well, as I said now I have one it's become indispensible. I'll probably start a thread later showing a few shots using one, I was finding a few Springtails and got a good one (better quality than the attached images!) of the jumping apparatus earlier.
