Brimstone.
September 4, 2011 in Biopedia, Butterflies by PaulS
This single-brooded butterfly can be found in most months of the year, although peak flight times are in April and May as the hibernating adults emerge, and again in August when their offspring reach adulthood. Autumn is a good time to see this species as the adults are avid nectar-feeders as they build up their fat reserves in preparation for hibernation.
Fairly ubiquitous to our area and fairly conspicuous. This is a big butterfly which can be easily identified by its yellowy-green colouring. Look for them feeding on any common wildflower.
