Common Blue Butterfly- the most likely blue butterfly to be spotted in the UK, (outside  of parks and gardens, where Holly Blue is more prevalent- see earlier post). The male has bright blue upper wings but the female is predominantly brown, with very variable degrees of blue. Both male and female have patterned underwings, with the orange marks distinguishing Common Blue from Holly Blue. A small but strong-flying butterfly it even turns up in Orkney and  on wasteland or wild grassland anywhere in the UK except the high mountain. A gorgeous sight, with two broods yearly, populations vary widely from year to year. I’ve seen far fewer this year. Caterpillars feed on Clover and Bird’s Foot Trefoil. Conditions: Sweltering day. Temperature: Max 26- Min-16 C.
