Sigara nigrolineata
This record describes Sigara nigrolineata (species). Recorded family: Corixidae. Recorded order: Hemiptera.
Identification and Appearance
A smaller species, length 5–6.5mm, with 7-9 pale lines on the pronotum, a pala with a single row of pegs and a more or less triangular xiphus. The male of S. nigrolineata has a facial depression below a transverse keel (or ridge) that is level with the bottom of the eyes. A widespread species which is found in upland and lowland areas in a wide variety of ponds and smaller aquatic habitats like water troughs. Often one of the first species of water boatman to colonise new habitats. All year round, with new adults emerging in July. Overwinters as an adult and there are two, possibly three, generations per year. Widespread and fairly frequent in Britain. No additional images available for this species.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Sigara nigrolineata. Species-specific details appear above.
Group overview
Hemiptera (true bugs) includes over 80,000 described species across cicadas, aphids, leafhoppers, shield bugs, and bed bugs. Aphids alone cost global agriculture an estimated $2.5 billion annually in crop losses.
Ecological role of the group
Many Hemiptera are essential food sources for birds and predatory insects. Cicadas provide massive nutrient pulses during emergence events - a single Brood X emergence can involve trillions of individuals across 15 states.
Economic and practical significance of the group
The brown marmorated stink bug (Halyomorpha halys) caused $37 million in apple crop losses in a single year in the U.S. Mid-Atlantic region. Bed bug infestations in the U.S. increased by 500% between 2001-2010, costing the hotel industry hundreds of millions annually.
Recorded sources for this group: USDA, EPA, University research. Imported estimates may describe particular regions or reporting periods.
