For correct determination of Coppers (Lycaeninae), a subfamily of the Gossamer-wing butterflies (Lycaenidae), it is important to pay close attention to the darkness of the wings. This is particularly important in females, which are sometimes difficult to recognize. Butterflies are often fiery red at the top of the wings, and in many species, there is a violet glow present.
Small Copper – 2016 (NL)
The Small Copper (Lycaena phlaeas) is a butterfly that flies around in three generations throughout the year, from late April to late June, from late June to early October and from early September to late October. Males are territorial, often choosing a piece of bare ground or a stone awaiting passing females. They behave aggressively towards any passing insects, returning to the same spot when the chase is over. Identification is fairly straightforward with the top of the rear wing being light grey or dark (summer brood) with an orange-red band in the inner edge zone. The top of the front wing is orange-red with black dots and a dark wing edge. The wingspan is 32-35mm. Host plant: Sorrel. Dutch name: Kleine vuurvlinder. Frisian name: Lytse fjoerflinter.
