Its preferred habitat is damp, marshy, woodland areas and I suppose that may explain why they tend to occur in the west of the country which is generally wetter.
This species spends much of its life as a caterpillar. The adult butterflies are on the wing for a period of about six weeks during June and July. Their eggs will hatch in July and the caterpillars will live through to the following May before becoming chrysalises.
This week I heard that there were a lot of Small Pearl Bordered Fritillaries at a Scottish Wildlife Trust reserve in the Scottish Borders. On Tuesday I headed down to Gordon Moss to take a look for myself. I had been sent detailed instructions on how to find the reserve and then whereabouts on the reserve to look. No sooner had I arrived at the gate into the field I saw my first one and over the course of an hour I saw about 40 of them.
