Biology

Adults of this single-brooded species fly in sunshine throughout July (2), when the eggs are laid. The caterpillars resulting form this brood are present from August to May of the following year, and feed on meadow vetchling and bird’s foot trefoil. They over-winter once or twice as a caterpillar before undergoing pupation(4).
