Status: Widely scattered and very local; not recorded from Scotland, old records only from Wales and Ireland. Scarce (Notable A)
Habitat: Calcareous grassland, unimproved grassland, maritime cliffs.
Host plant: Various Scrophulaceae i.e. figworts and mulleins.
Overwintering: As adults
Food: Adults on leaves, larvae probably at roots.
Other notes: Adults parasitised by a braconid wasp larva (probably Perilitus sp.) and an unidentified nematode.

Status: Widespread but uncommon in England & S. Wales. Scarce (Notable B), appearing to have declined long-term in eastern England in particular.
Habitat: Woodland clearings and calcareous grassland, chalky hedgerows, sand, shingle, and possibly river banks.
Host plant: various Boraginaceae, especially vipe'rs-bugloss (Echium vulgare) and hound's-tongue (Cynoglossum officinale)
Overwintering: As adults
Food: Boraginaceae: adults on leaves, larvae probably at roots
Other notes: Adults parasitised by a braconid wasp, probably Perilitus sp.

Status: Widespread, mainly in England and Wales
Habitat: Woodland, especially clearings & rides; also chalk grassland, fens, moorland and grassy sea cliffs.
Host plant: Various Lamiaceae, mainly wood sage Teucrium scorodonia. Also collected from oaks.
Overwintering: Probably as adaults and larvae (two generations per year)
Food: Wood sage: adults on leaves, larvae at roots.

Status: Widespread and common
Habitat: Various
Host plant: Plantains (Plantago spp.), occasionally on other plants.
Overwintering: As adults in leaf litter, moss and grass tussocks.
Food: Adults on leaves, larvae in roots or on leaf petioles.
Other notes: Dissection of genitalia needed for separation from L. kutscherae & L. plantagomaritimus. Adults parasitised by larvae of a braconid wasp, probably Perilitus sp.

Status: Rare: restricted to the New Forest and East Dorset.
RDB Category: Endangered (RDB1)
Habitat: Shallow boggy pools and pits, and peat bogs (where bladderwort occurs)
Host plant: Lesser bladderwort (Utricularia minor) and possibly other Utricularia spp. Adults may be found on grasses in boggy areas.
Overwintering: As adults
Food: Adults on fine leaves and stems above the water surface, larvae on stems and leaves (partially or wholly submerged, sometimes with part of the abdomen exposed to the air).
Other notes: Unlike other British Longitarsus, antennae and legs almost entirely dark brown to black, plus pronotum & elytra entirely black without yellow markings.
