I was about to do a different subject for today’s blog when along came this female Common Blue Butterfly and started feeding a a Daisy on our uncut lawn! I don’t remember ever seeing a Common Blue in our Sheffield garden so maybe last summer’s heat helped this species locally. Females have variable amounts of blue and brown on their upper wings, while male are all-blue on upper-wings (I include a photo of a male for identification purposes, even though I haven’t seen one here- yet! The photo is from a Sussex garden). Common Blue caterpillars feed mainly on Bird’s Foot Trefoil, and sometimes on white Clover, Restharrow etc. The adults love being in the sun, on grassland, waste ground, road verges etc. They are fairly widespread, living up to their name. Conditions: Cloud giving way to sun. Temperature Max 14 Min 7C.
