Delphacidae - Eurysa lineata?

[JRsbugs]

Hi,

This was about 3mm long including wings. Taken on 7th June. Is this correct? It looks to have the brown area at the top of the wings.

I only got this 'good' pic, near impossible in the dull conditions.

Has this been missed? I would appreciate any thoughts on it, thanks.

Hi Janet,

You really want Joe or Tristan but in my non-expert opinion the prominence of the keels on the head suggests something like Javesella pellucida.

Hi Steve,

That was the other one I juggled with, and I agree about the head. The wings of Javesella pellucida are said to be brownish or whitish tinged, but on mine they don't look a lot different to the pics of J. pellucida.

After weighing up everything, I was swayed by the brownish area as stated for Eurysa lineata which J. pellucida doesn't look to have. I can see something brown which resembles at least one of the pics of Eurysa lineata anyway!

Macropters are much darker on the scutellum, with a characteristic brown area on the inner angle of the forewings.

Yep, it's a macropterous J. pellucida (the vertex does indeed give the game away). The brown corner on the forewing is actually just the abdomen showing through, in a patch without the whitish hind wing getting in the way!

Thanks Joe!

Thanks Steve!

Evening Janet,

Good to see you back posting! A nice shot given the dull conditions you describe, I don't bother shooting low-down as I know my camera will do that thing where pale colours become white, the screen lags with a low frame-rate and I'll get just 1/20th sec...

I agree with the ID of course, but what a good record Eurysa would have been...

Take care,

Jason
