I’m not an expert in insects and microfauna.
I distinguish a bee from a beetle only because the first is dangerous and the second is only ugly.

Perhaps, butterflies are an exception (until someone more expert than me will teach me that some of that I consider butterflies actually aren’t…).

All these photos are token by free-hand, often at real-life magnification’s limit.
A pair are made without specific macro lenses, but only with tubes to have a closest minimum focus distance.
