Stygnocoris fuligineus
This record describes Stygnocoris fuligineus (species). Recorded family: Lygaeidae. Recorded order: Hemiptera.
Identification and Appearance
Length 2.5 to 3.5 mm. Stygnocoris species are small ground bugs in which the pronotum and forewings are covered in fine hairs. The pronotum is punctured throughout, and the front femora lack spines. Stygnocoris fuligineus and the closely related Stygnocoris sabulosus are very similar; this species is distinguished by the duller aspect of the dorsal surface, the much shorter pubescence and the darker femora. It is always macropterous. Detailed examination of the specimen is needed to identify the species (a photograph alone is not normally sufficient because key features are too small or hidden). Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed. Adult: All year. There are probably two generations a year which mature in the summer and autumn. 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 Stygnocoris fuligineus. 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.
