Gracilimiris rubrolineatus
This record describes Gracilimiris rubrolineatus (species). Recorded family: Miridae. Recorded order: Hemiptera.
Identification and Appearance
Superficially similar to G. litoralis and G. strigosus in having distinctly dark-spotted hemelytra with scattered, black, bristlelike setae, but differs from both species in the smaller size, the more sparsely spotted and less-dense, bristlelike setae, especially on clavus; the pale antennal segment I usually with only slightly darker brown mottling, but some specimens becoming much darker and forming a dark ventral line; the dark brown to fuscous segment III with only the base pale or whitish; the pale or whitish median line on the pronotum, narrowly bordered with diffused red accents; the white lateral pronotal carina bordered with a narrow red line dorsally and ventrally; and the male genitalia.

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