Identifying features
Wingspan: 28-36 mm. Purple-edged copper is a rather large fritillary.
Similar species
Purple-edged copper can likely only be confused with scarce copper (Lycaena virgaureae). However, the male is easily distinguished by the fact that purple-edged copper has a clear spot in the middle of its wings, which the male of scarce copper does not.
Distribution
Purple-edged copper was previously a common butterfly throughout Denmark, but today it only appears relatively common in Middle and North Jutland. In East and West Jutland, it is more rare, and in South Jutland, it is almost extinct.
Biology
The eggs are laid individually on the plants common sorrel (Rumex acetosa) and sheep's sorrel (Rumex acetosella). The larva hatches after 1-2 weeks and feeds on the plants until the next moult, after which it hides deep within the vegetation to overwinter as a larva.
