The Campion Sideridis rivularis


Family Noctuidae » Subfamily Hadeninae » Sideridis rivularis (Fabricius, 1775) 73.276 (BF2166)
Wingspan 27-30 mm. Similar to the Lychnis (H. bicruris), but tends to have the two forewing stigmata joined at the base. Fresh specimens can be quite attractive and usually have a purplish suffusion. The larva feeds internally in the seed capsules of various campions (Silene) and catchfly (Lychnis). The adult flies in May and June, but in the south there is a second brood in August and September. Found in a variety of habitats, including roadside verges, damp meadows, moorland and sea cliffs. Distributed widely over much of Britain, and fairly common in places.
