| Comment | Normally midges live for about 10 months but fit in 2 breeding cycles each year, which gives the big peak in late summer (i.e. the ones you get bitten by in August are also the offspring of the ones that hatched in May)
However if you have a mild enough spring (so the first cycle is early) and a mild enough autumn, then they sometimes get 3 generations in, and you get a late surge just before the weather finally cools enough to kill them off
It's not usual, but this year seems to have had just the right conditions for midgy grandkids |
