Temps associated with insect hatches
 

I have been looking for temperatures associated with insect hatches. So far
I really have not been able to find anything. Do any of you have any such
info. Water and /or air temps, degree days whatever. Or also environmental
indicators such as plant buds/blooms associated with insect hatches or other
Phenology.

This book is still on my list. A fishing friend recommended it:

Merwin has a section in one of his books that covers some Phenology
too. Namely:

Hendricksons and Forsythia, Shad flies and shad bushes (also
corresponding with the shad run in the Catskills), peonies and
sulphers, cardinal flowers and tricos, and fringed genetia and bwos
in the fall.

On the temps side, I have always observed Hendricksons start to pop
between 50 degrees F and 52 degrees F (water temp). Trico spinners
start falling when the air temp hits 68 degrees F. These observations
may well be localized.

A water temp of 13-14 degrees Celcius seems to be the magic number
down this way.
(Purely anecdotal of course). There are sparse hatches at lower temps
and typically of
midge (coldest) and caenis ... as the temps rise though more and
larger species come off.
