Grypocoris stysi
This record describes Grypocoris stysi (species). Recorded family: Miridae. Recorded order: Hemiptera.
Identification and Appearance
Length 6-8 mm. A conspicuous bug. The chequered pattern of light yellow-white areas and striking orange-yellow cuneus make confusion with other species unlikely. Usually on Nettles in woodland, and sometimes umbellifers and White Bryony. Eggs hatch in May and nymphs become adult in June and July, rarely surviving much beyond August. The adults and larvae feed on both flower heads and small invertebrates such as aphids. Common and found widely throughout Britain.

About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Grypocoris stysi. 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.
