Scorpion Fly

Scorpion Fly ♀ & ♂

There are 3 species on the UK list, and before digital technology careful examination with a microscope or a good hand lens was required. Today it can be seen from good macro images that it is not always necessary as in  P. germanica has thickened parallel hypovalves on male genital capsule, which can be seen my image that they are calliper shaped identifying it as P. communis. (The wing pattern can also be decisive  factor.)
