Luperina
Boisduval, 1829
Luperina is a of in the Noctuidae. The genus includes several with documented , notably Luperina nickerlii (Sandhill Rustic) and Luperina testacea (Flounced Rustic). Some species formerly placed in Luperina have been reassigned to the genus Resapamea. Species in this genus are associated with grassland and have larvae that feed on grasses.

Habitat
Coastal sand dunes, saltmarshes, sandy heaths, calcareous grasslands, and open grassland near water bodies. Some occupy highly specific microhabitats: Luperina nickerlii leechi is restricted to a single sand and shingle bar in Cornwall, UK.
Distribution
North-west and central Europe, with records from Czech Republic, Andorra, Bosnia and Herzegovina, Croatia, France, Germany, Great Britain, Ireland, Italy, Kosovo, Macedonia, Montenegro, Poland, Portugal, Slovenia, and Spain. Britain supports the northernmost colonies. Widespread in Britain but less frequent in Scotland.
Seasonality
fly from late July through October. Luperina nickerlii adults fly late August through October; Luperina testacea adults emerge late July to early October.
Diet
Larvae feed on grasses. Luperina nickerlii larvae feed on Festuca ovina, Festuca rubra, Elytrigia juncea, and Puccinellia maritima; leechi specifically feeds on Elytrigia juncea. Luperina testacea larvae feed on roots and lower stems of various grasses. do not feed.
Life Cycle
laid at bases of grasses or inside in late summer or autumn. Larvae overwinter inside grass stems or crowns, feeding slowly through winter; in spring they feed underground on rhizomes and roots. Pupae usually have a silky case around them. emerge in late summer to autumn.
Behavior
; attracted to light. Coastal are weak fliers and only fly on nights with light or no winds. Luperina nickerlii subspecies demuthi is uniquely adapted to survive under brackish water. Subspecies leechi exhibits cryptic coloration with pale silver and brown forewings matching pebbly shingle substrate. Luperina testacea is frequently trapped at light, predominantly males.
Ecological Role
Larval herbivory on grasses contributes to nutrient cycling in grassland and coastal dune .
Human Relevance
Subject of genomic research; Luperina nickerlii leechi sequenced due to conservation interest as a geographically isolated . Luperina testacea is commonly recorded in trapping surveys.
Similar Taxa
- ResapameaFormer Luperina (L. enargia, L. innota, L. passer, L. stipata, L. trigona, L. venosa) have been transferred to this based on morphological and genetic reassessment.
Misconceptions
The name 'Luperina' has been used for both a (Lepidoptera: Noctuidae) and a subtribe (Coleoptera: Chrysomelidae), but these are unrelated . The moth genus Luperina was established by Boisduval in 1829, while the beetle subtribe Luperina (now typically treated as subtribe Luperina within tribe Luperini) was established later by Wilcox in 1965.
More Details
Chromosomal biology
Luperina have 31 chromosomal pseudomolecules (30 + Z ). Luperina nickerlii leechi has an unusual ZO sex chromosome system in females (lacking a W ), associated with a skewed sex ratio of 30:70 male:female.
Conservation status of subspecies leechi
Luperina nickerlii leechi occupies an extremely restricted range (Loe Bar, Cornwall, approximately 430m x 250m), isolated by at least 300 km from other nickerlii , making it vulnerable to local extinction.
