• Leptoglossus occidentalis

  Western Conifer Seed Bug, WCSB

  Leptoglossus occidentalis, commonly known as the Western Conifer Seed Bug, is a leaf-footed bug native to western North America that has undergone dramatic range expansion. Originally confined to the Pacific coast region from California to British Columbia, it began spreading eastward in the 1950s, reaching the Atlantic coast by the 1990s. The species has also become invasive in Europe (first detected in Italy in 1999), Asia, South America, and elsewhere. Adults are notable for their loud, droning flight and tendency to seek shelter indoors during autumn, where they become nuisance pests. They feed on conifer seeds and developing cones, particularly of pines, and can cause significant damage in seed orchards.

• Lygaeus

  seed bugs, milkweed bugs

  Lygaeus is a genus of seed bugs in the family Lygaeidae, containing over 60 described species. Members are characterized by aposematic coloration—typically combinations of red, black, gray, and white—that advertises chemical defenses. Several species, notably L. kalmii (small milkweed bug), sequester cardiac glycosides from host plants, rendering them unpalatable to predators. The genus exhibits diverse feeding strategies ranging from seed-feeding specialization to opportunistic scavenging.

• Lygaeus kalmii

  Small Milkweed Bug, Common Milkweed Bug

  Lygaeus kalmii is a seed bug in the family Lygaeidae known for its bright orange-red and black aposematic coloration. Adults measure 10–12 mm and feed primarily on milkweed seeds and flower nectar, though they exhibit dietary flexibility including scavenging on dead insects and feeding on seeds of other plants such as composites. The species sequesters cardiac glycosides from milkweed, making it unpalatable to predators. Unlike the migratory large milkweed bug (Oncopeltus fasciatus), L. kalmii is non-migratory and overwinters as adults. Two subspecies are recognized: L. k. kalmii in western North America and L. k. angustomarginatus in the east, distinguished by differences in the white markings on the membranous portion of the forewings.

The species is specialized on Senecio species as host plants, from which it sequesters pyrrolizidine alkaloids that render it distasteful to some predators. It exhibits complex territorial and mating behaviors centered on host plant patches, with males defending high-density areas where females preferentially oviposit. The species shows pronounced sexual dimorphism in flight behavior: females conditionally histolyze flight muscles based on resource availability, while males retain flight capability throughout life. It has a broad distribution across the Americas and has been introduced to Oceania.

• Nysius

  false chinch bugs

  Nysius is a large genus of seed-feeding true bugs in the family Lygaeidae, commonly known as false chinch bugs. The genus contains approximately 100-106 described species with worldwide distribution. Several species are significant agricultural pests, including N. huttoni (wheat bug) in New Zealand and N. cymoides in Europe and Turkey. A unique Hawaiian radiation contains 26 species, including two flightless, predatory wēkiu bugs (N. wekiuicola and N. aa) that feed on dead and dying insects on high-elevation volcanoes. Most species feed on seeds and plant fluids, though some exhibit atypical feeding behaviors.

• Nysius raphanus

  False Chinch Bug

  Nysius raphanus, commonly known as the false chinch bug, is a small North American seed bug in the family Lygaeidae. Adults measure no more than 1/8 inch (approximately 3 mm) in length.
