Aposematic flies

[Scotaidh]

We know not to annoy unidentified flies with yellow and black banding and we know not to eat ladybirds with their black spots on a red background (or vice versa), but frequently wet flies which perform very well exhibit combinations of black with yellow, red and orange.  Admittedly I can't think of anything a trout might find under the water that has warning colours, although many terrestrials do.  It is little wonder then if trout do not adhere to the rules of what doesn't look tasty, commonly found in land or saltwater.

Any thoughts?

Does anyone have a fly which doesn't catch fish which has typical warning colours Incorporated?  Peter Ross?

At the speed I pull my flies through the water- I doubt very much that the troot have a chance to consider colour

Simply that it looks roughly the right shape and size.

The Peter Ross is most certainly aposematism in action.

Great post Scotaidh   :lol:

Looks like it has its head buried in the leaves. I see the back legs, is backside and what might be its right front leg the rest isn't showing up.

Thanks Bob I missed that.

I was seeing it, I thought it was one of those pointy headed ones but my brain wouldn't connect the head with the rest of the body although I could 'see' it.

I have a couple of wasp patterns in my box and on occasions the trout love them.

I do think that there are light/colour combinations conditions that scare trout and grayling. I was on a stretch of the Wiltshire Bourne and put on a hares ear nymph with a fluorescent green tail which dispersed a shoal of grayling very quickly indeed. I have since read an article by Charles Jardine about fishing ultra clear lakes in Canada during a world championship round where he said anything fluorescent terrified the trout.

Well, in the interests of science, I'll give this a thrash on the water next season.
