Another New Butterfly

The Brown Argus Aricia agestis is another new butterfly that Trust members have found in Ox Close Wood and in fields in East Keswick. This is great news – showing that the management of our reserves is being rewarded with these successes (see Silver-washed Fritillary, below). The caterpillers’ foodplant is usually Common Rock Rose but more recently they have started to use various geraniums, including Meadow Cranesbill, of which there is plenty in the parish.
