Day-flying micros

Today's sunshine brought out some of the early-season micros.  Seen while carrying out a butterfly transect in Finemere Wood, Bucks were more than 30 examples of the primitive micro Micropterix calthella.  The adults are unusual in that they feed on pollen and were mostly favouring garlic mustard, but some were also seen on wood anemone and celandine.  The long-horn moth Adela reaumurella was also starting to appear there in some numbers, mostly flying above blackthorn, while Incurvaria masculella was recorded flitting around hawthorn.
