I was going to watch one of the rugby internationals yesterday morning but, when I woke up to sunshine streaming through the window, I grabbed my net and drove to Walter's Copse, Newtown to survey for hoverflies.
'....it's really super weird. The
green oval-shaped thing with the spines is the actual creature. That
big crinkly brown thing on its back? That's a mass of dried excrement.
Poop. I couldn't make this stuff up. The larva actually holds this thing
up over its back with a special "fork" on its hind end, and it can wave
it around at will. Various internet sources suggest that this is some
sort of defense mechanism, or a means of camouflage. Either way, blech.
