Hello,

Help requested to Id the attached. All photographed in East Sussex, South of England.

I thought A might be E. pertinax (broad facial stripe )
and B might be E.abusivus. The other two I can't work out.

Can you put me out of my misery and assist with my further education.

Many thanks Gordon

tenax has the two bands with hairs on the eyes (well visible in both specimens)

nemorum/interrupta has a small, dot-like pterostigma

pertinax has yellowish tarsi
