Common Green Capsid Lygocoris pabulinus (Linnaeus, 1761)

Lygocoris pabulinus
  • Cambridge, Gwydir Street: 16 Jun 2001
  • Subfamily: Mirinae. Tribe: Mirini
  • Length: 6mm
  • "Found commonly and abundantly throughout the British Isles this bug has two generations a year and two groups of host-plants: woody plants in which the egg overwinters and on which the young spring larvae feed for a short time, and herbaceous plants where most of the development occurs. Woody hosts include hawthorn, apple, currant, plum, cherry and lime; the herbaceous ones include nettle, creeping thistle, groundsel, dandelion, black nightshade, potato, bittersweet, white deadnettle, sunflower, dock, fat hen, meadowsweet, rosebay willow-herb and common cow-wheat; plants such as raspberry, rose and elder may serve as hosts throughout the year.
    L. pabulinus is often a pest. The young larvae of the first generation damage currants, plums, apples, gooseberries and pears, their feeding punctures producing brown spots which form holes as the leaves grow or blemishes on the fruit, especially of gooseberry and pear. The later stages of the first generation and all stages of the second attack blackberries, raspberries, strawberries, potatoes and sugar-beet." - Southwood & Leston

Heterotoma planicornis (Pallas, 1772)

Heterotoma planicornis
  • Cambridge, Gwydir Street: 10 Jul 2007
  • Subfamily: Orthotylinae. Tribe: Orthotylini
  • Length: 5mm (not including the antennae)
  • Distinctive with its thickened antennae extended forward
  • Often referenced in English authors as Heterotoma merioptera (Scopoli, 1763), but the prevailing view appears to be that the name H. merioptera correctly applies to a species confined to eastern Europe, while H. planicornis extends into the north-west of the continent. The original types of both species are lost (and they have sometimes been treated as synonymous). Kment & Bryja (2006) (link) discuss the history of nomenclature at length and designate neotypes for the two species.
  • "In southern England it is abundant on rank vegetation, especially nettles, and on various shrubs and trees. The young red larvae hatch from the overwintered eggs at the end of May or in early June; the majority reach the adult stage during the last half of July and some adults have been found as late as October. Both larvae and adults are predatory on aphids and other small insects, besides feeding on buds and unripe fruits of various plants." - Southwood & Leston (as H. merioptera)
