[ID] Beetle, young Planthopper and Psyllid please!

[Jason Green]

Hi all,

I've just had another productive field trip, despite a mild and overcast sky.

21/03/2010

Beetle under log
Unfortunately there was no head or pronotum. With these I assume it would have reached 12mm - that's a 5mm grid. That leg - it almost appears paddle-like, and is hairy. Any ideas from the body/leg shots? The middle one shows the highly-punctate dorsal surface to the elytra.

21/03/2010

Psyllid - Cacopsylla sp.?
Found on, I think young leaves of a Nettle. It hopped readily. c3.5-4mm

21/03/2010

My first deltocephaline Planthopper of 2010 - Spring is here!
I found a Euscelis incisus nearby - is this the juvenile?

Thanks for looking!

Take care,

Jason

They're the forelegs of a male with tarsal pads. These are prominent on some carabids particularly Harpalus sp.. However, the elytra strike me as more tenebrionid ....
... some people can identify beetles to species on far less than this .... sadly, I'm not one of them. Good luck.

[Jason Green]

Thanks Paul, I did think it appeared too round/curved. Where are all these Carabids, then? In the last fortnight I must have turned over about 10 logs or more - but not a single Carabid!! I see more on the 'Net... (plenty of other goodies, though)

So I suppose I'm looking for a 12mm Tenebrionid - I agree - that has prominent tarsal pads. When I said it had paddle-like structures, I wasn't intimating it being of aquatic descent.

Thanks again

[Jason Green]

How about a beetle akin to Nalassus sp., such as Nalassus Laevioctostriatus or similar? That's about 12mm max, prominant tarsal pads on the front two pairs of legs, common, found under bark, and is from the Tenebrionidae family.

I should have retained the specimen to put under the microscope, but I placed it back where I found it. I know where that was, so I'll try for additional photographs next week if possible.

Thanks for the steer!

That's just a feeling - hopefully someone will recognise more ....
I would think that most carabids will still be in hiding in the ground but this is the time (and weather) when they will start emerging although you won't see too many until May .... but who's to say?

.......

That would be my first thought! I have some specimens somewhere so I'll have a look .... but don't hold your breath!

I'd agree the nymph is E. incisus - this is a deltocephaline leafhopper (planthoppers are Delphacidae)

Nice Psyllid photo Jason.

I notice that there are a few white blobs visible under the wings. I've often seen this in photos of my own and wondered what they are - any ideas?

Anyother views of the psyllid? I can't quite see the venation clearly enough to get very far, although I'm pretty sure it's Triozidae. The sharp colour change in the antenna isn't right for urticae, though (although the rest of the colouring could be, as could the genital segment).

The white splodges are waxy secretions, Bruce - what exactly they're for is another matter!

[Acutipuerilis]

On balance, it may be Trioza silvarnis (UK form of curvatinervis), but don't take that as definite. Another view would definitely help!
