Dear Fredrick,

Dear Fredrick,

I think the most resemble insect to your photo is the numph of Abisares viridpennis. Please see the attached photo. In fact, I could not know why your photo is brown and not green?

 I agree with Mehmet that its speculative that, tell something about its species  via only a photo..

Regards,

Wafaa

yeah, I collected both brown and green, however I just attached the brown specimen
