Hello,
is this a species of Psylloidea inmidst its progeny ?
Viviparia ?

Or ist this a flying Aphidoidea ?

and on the leaf beside :
Psylloidea with the flat elder form of its larva ?

---

It's an aphid. What was the host plant?

---

What's the trick to tell apart Aphid and Psylloid ?

Host plant was Acer psuedoplatanus.

Besides the two aphids in the secon picture you can see five extremely flat larvae : but these are psylloidea ?

Hi Joerg, the flat ones on the 2nd image could be psylloid larvae but it could be mites, too. For me it's not possible to see itn clearly enough.

Greetings, Eric

thanks

Remember that psyllids are called jumping plant lice - so they are usually seen with their short and powerful hind legs tucked under their body, ready to jump. Aphids crawl (or fly), so they have easily visible long hind legs. Also aphids tend to fold their antennae back, but psyllid antennae stick forward.

I think these are Periphyllus species, The first picture is probably P. acericola, and the second picture P. testudinaceus. (Based on leg and body colour.)

Thank you - I see ...

Greetings,

Joerg

another try - to see what I've learned :
Psylloid running on Acer, spreading its antennae forward...
But strong hind legs ?? - I don't Know. Maybe aphids spread their antennae forward too when running ...

Hi Jörg, hind legs are long and weak: a winged aphid.
Could be Drepanosiphum platanoidis - the paler generation from late summer.
