Habitat
In the British Isles, one or two generations annually, with adults seen at any time from May to September. Larvae feed on bedstraws and various legumes such as clovers, trefoils, lucerne and meadow vetchling, primarily in June and July and from mid-August through September, though in Ireland and northern Britain larvae occur in July and August. The species overwinters as a pupa. This species flies both during the day and also at night when it is attracted to light.
Reproduction
The final instar larva is pale green with white lines, including a strong lateral line and thin dorsal lines along the body. Abdominal segments A1 through A5 have a strong white line across the rear end of each segment that ends just above the lateral line.References:
