Busy Orange Tips.

The first Orange Tip,a male, flew around my garden today.Most years I do not see this species in my garden until May, so much earlier than expected.Activity of this species has been evident since the first week in April when at Ventnor I came across a female taking great interest in the Honesty plants.She was soon joined by a male who fluttered feverishly around her.Her response,in this instance,was a rejection of his advances in typical Orange Tip fashion.Females who have already mated and want to shoo away a male will  flatten their wings and raise their abdomen.This is followed by an opening of the genital valve to release anti-aphrodisiac hormones to discourage the male.
