April 1st 2011 stands out as the evening I had my first really good micro of last year, Pammene giganteana, along with 13 other species. So more out of interest than expectation, I thought I’d try the same site on same date this year as it’s nearby, just to see what turned up. Using the same traps as last year: – very little. I gave up after an hour, having caught just 13 moths of 5 species and no micros.
The difference? – The weather? – Mild & cloudy last year, clear, bright moon, 6 deg. this year.
Or the season? – 3 or 4 weeks early last year, maybe less so this year.
