Caddis Fly

[georgedingwall]

Hi all,

Here's an image of the head of a Caddis Fly. I'm not 100% sure of the exact classification, but the wing pattern looked a lot like Trichoptera Limephilus Lunatus.

My fly book suggests counting the spurs on the tibiae, but I'm not quite sure what are spurs and what aren't, so I'll go with my guess.

The field of view in this image is about 3mm.

Hi Ken,

I am not familar with a caddis up this close but I can tye a fair tent wing imatation.

I've never really been into fly fishing. As an ex Navy man, I always favoured sea fishing.

I wonder what a Caddis fly really looks like to a fish. I don't think there are many macro photographers in the fish kingdom.

Bye for now.

Hi Doug,

They are always crammed with all sorts of things to look at and very fine detail

I agree Doug. In this image, I am amazed at the various surface textures on the head between the eyes.

It seems to go from a fine fur like appearance near the eyes, to something that looks a little like toad skin in the middle. I wonder what those little green patches are for?

I think I also see a couple of structures that look like Occulae. I didn't know flies had them.

Bye for now.
