Its always a highlight in my Butterfly calendar to look for the arrival of the Marbled White Butterfly.
The calendar on my Mac issued a warning message over the weekend, "Marbled White emerges".
Their flight time is mid June to mid August, so without further ado I went to the location where they have recognised colonies.
Sure enough I found several males on the wing, but it is early days as yet.
It was during the morning and this normally is a busy flight time for this species, but due to various cloudy periods I was able to find some of them pitched.
