A harvest festival of ripe fruit and colourful butterflies

 Apples, pears and plums are ripening faster than we can eat them, so the bird table has been taken over by butterflies feeding on the fermenting juice of over-ripe fruit.

There were are least twenty red admirals and half a dozen comma butterflies getting legless on alcoholic fruit juice in this afternoon’s warm sunshine in the garden. When they are in such a lethargic, inebriated state butterflies are very easy to approach and if they do fly they settle again almost immediately.

Comma butterflies seem to have a particular liking for pear juice

As sometimes happens, a fight broke out between drunkards when this red admiral and comma butterfly were competing for the same feeding cavity in a pear. Wing blows were exchanged and the comma prevailed. It seems even some butterflies can become aggressive if they over-indulge with alcohol, although most seem to just become semi-comatose, to the point where they’ll crawl onto your finger rather than fly away if you poke them.

Silver birch seeds

 Silver birch seed catkins are ripening now and fall apart at the slightest touch. Their seeds are an important food resource for several small finches, including siskins, goldfinches and redpolls.


When the catkins disintegrate they separate into woody, arrow-shaped bracts, releasing the much smaller seeds that are surrounded by a broad translucent wing. They can be carried long distances on a windy day - one of the factors that make this tree such a prolific coloniser of open habitats.
