Antero-dorsal hairs on the hind femora including many at least as long as half the depth of the hind femur, these longer hairs present on more than half the femur length.

Distribution

Palearctic Fennoscandia South to central France. Ireland eastwards Europe into Russia and the Caucasus then to Siberia.[9][10]

gollark: IIRC it can be proven that no polynomial makes infinitely many primes like that.
gollark: It generates primes for a while then doesn't.
gollark: If it was not for knowing that it didn't always produce primes we may have been fooled.
gollark: Being highly efficient, everyone just put in increasing values until a composite number came out.
gollark: Once in a maths lesson we were doing (dis)proof by counterexample and got the traditional x²+x+41 thing.
