Spotted yellow nymph - looks like froghopper

Found on Vinca - but there's a lot of other plants close by.

Size: Pic1 includes a scale bar.

This looks to be an early instar nymph of some type of 'hopper. I've done a fair bit of Googling and whilst I've found plenty of yellow nymphs, none seem to have black spots on them.

Help with identification much appreciated.

Hi Bruce,

Great to see you, and your crisp images, around

Any meadow/grasses?

You didn't lift it from "spittle" and not tell us, did you?

Certainly I'm always having trouble with all your British frog-, leaf-, plant-, whateverhopper categories so I won't go there

I'm having a hard enough time recognizing even a bare minimum of adult 'hoppers', so any attempt at nymphs is bound to to be headed full speed toward a concrete wall, but hey ... who said skulls can't brake concrete? Gotta try anything one time

Anyway, having a glance through the key linked below and then looking at images of adults, as there are very few images of (correctly?) identified nymphs to be found on the net, comparing morphological features such as head shape etc, I would tentatively land on Aphrodinae and possibly maybe the likes of Aphrodes makarovi or some other Aphrodes.

Very tentatively indeed however, as that takes a few shortcuts in the key - biggest one being me not being able to recognize any ocelli on the nymph and still going for that because I liked the end results better (at 2mm the nymph seems (way?) too big for an early stage Typhlocybinae and all the head shapes of those don't seem to come close enough, and some other twists and turns down that path all end up with shapes that are a worse fit still).

While browsing/comparing please note that the Aphrodinae are a subfamily of the Cicadellidae, not Aphrophoridae (as the similarity in the names might put you on the wrong track).

Key used: Zenner, Gudrun; Stöckmann, Marlies, Niedringhaus, Rolf (2005) Preliminary key to the nymphs of the families and subfamilies of the German Auchenorrhyncha fauna. (PDF - 7MB)

Lists of British species: Fauna Europae - Aphrodinae, British Bugs.

Some galleries: Gernot Kunz, British Bugs, Tom Murray, Keiji Morishima (Japan).

Hope the links help, as my knowledge of these is grossly insufficient. One other option would be to post the images in a German forum where Herbert Nickel reads, or send them to him directly.

Cheers! Arp

Hi Arp - Thanks for your help on this one and for those excellent links. The PDF key is terrific! I'll check and see what I can find for the Aphrodinae. I'll also sweep the Vinca from time to time to see if anything emerges that could be the adult form.

No there wasn't a sign of spittle anywhere in the vicinity of the Vinca - although I do agree it does look like a spittlebug .

BTW, I sent the pics off to Herbert Nickel as you suggested.

Thanks again.
Bruce

Excellent! I hope he comes up with something - please let us know if he does. Way too few reliably identified nymphs on the net, and as the key states it would greatly help to be able to ID those better too

Cheers! Arp

Arp,

I've heard back from Herbert Nickel. He's identified it as an Aphrodes, most likely A. makarovi (according to habitat). So looks like you were just about on the money with your identification.

Hi Bruce,

That was quick! Thanks for the feedback

There just isn't a smiley cool enough to express my pride with the close estimate!

Would you mind terribly to update the title and description of the images at some point, maybe even adding some keywords for Auchenorrhyncha, Aphrodinae or such to the keyword field? On WATW you can edit your images via the "Photo options" roll down menu at the top right of the image page

Thanks!
Arp
