According to this article we are likely to see fewer butterflies around this year because of last years wet summer. 2007 was the worst year for butterflies for more than a quarter of a century with numbers at a record low. This was mainly because butterflies do not fly in the rain and therefore they cannot reach plant nectar to feed or fly to breed. The charity Butterfly Conservation is hoping that we have a long hot summer this year so that numbers can recover. Unfortunately I think my cats are to blame for the lack of butterflies in my garden.
