Galgupha diminuta
This record describes Galgupha diminuta (species). Recorded family: Thyreocoridae. Recorded order: Hemiptera.
Identification and Appearance
From McAtee & Malloch: Usually completely black, but occasionally with pale spots at lateral margins of abdominal segments. Sixth [sternite of male] quite sharply angulate in center of anterior margin, and with a dense transverse brush-like strip of brownish-black erect hairs close to apex on central third or more ... Ventral exposure of hypopygium [=pygophore] copiously punctate, hind margin only slightly reflexed, deeply biconcave (Fig. 117); in the dorsal aspect the posterior rim of hypopygium on account of its bisinuation is well below the level of the lateral and anterior portions, the latter are moderately broad, with a wide shallow depression in middle of anterior rim, median excavation deep, the lateral walls abruptly declivitous.

Species notes from the sources
Etymology: Presumably referring to its small size. It is smaller (3.0–3.8 mm) than most Galgupha species.
About True Bugs, Cicadas, Hoppers, Aphids and Allies: the wider group
Order-level background for Hemiptera, the group containing Galgupha diminuta. 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.
