Does anyone have a chart or is there a section on the forum that charts the entomology of the types of fly hatching throughout the year in the UK. I can't seem to find one

If all you are after is a basic guide to what is hatching when, then the Pocket Guide to Matching the Hatch by Peter Lapsley is a pretty good starting point.

Boyd, dont apologise. nobody knows everything. first thread on this section has simple guide to the so-called 'mayflies'.

I agree with the above. I have the full size version and it's really useful. You can have a look at it on amazon books. Hey you don't sound thick mate, only way to learn is ask. I'm still asking after 30 yrs!

Here in darkest Yorkshire we have a quaint expression - "the only stupid question is the one you didn't ask!"

Hi Boyd, they say you can tell a clever man by the answers he gives,
and you can tell a wise man by the questions he asks.
My advice is John Goddards Waterside Guide. Good luck, RB.
