|Knot Grass, Westcott 1st May|
For those of you who have Emperor Moth females (or the pheromone lure), I would suggest that now is a very good time to get out with them and try for records away from home. It has been hard work here over the past couple of weeks since my first female emerged on 20th April but I have managed to 'assemble' single males at three or four sites. However, there was a sudden burst of male activity locally mid-afternoon yesterday when six 'wild' examples appeared at once to the caged females which had been outdoors in the garden since early that morning. Following the usual pattern here, with females appearing before males, my first home-bred male didn't emerge until 28th April (by which time nearly all the females were out - not quite sure what they might gain from that strategy). Today seems to have been peak male emergence amongst my captive pupae with 15 appearing so far. No great surprise that it is a late season for them here.
