hmm interesting pics

They look a lot like a horsefly that bit me last week. I expect someone will be along who knows exactly what is going on here.

Surprising

It's not an insect I've ever heard about before yet someone's produced a factsheet on it.

amazed by this one

facinating - great Id alan - not seen this before - and the fact sheet explains everything.
this is the value of this system - you learn something every day.
thanks
