Fitchia spinosula
This record describes Fitchia spinosula (species). Recorded family: Reduviidae. Recorded order: Hemiptera.
Identification and Appearance

The easiest field character for separating the two species involves the color of the integument surrounding the spiracle: concolorous pale in F. spinosula versus dark brown in F. aptera . Male parameres are distinctly clavate, as opposed to the slender, digitate parameres of F. aptera . On average, F. spinosula tends to be a little longer and more slender than its congener. The pronotal armature is variable, and overlaps with F. aptera , but in F. spinosula , there are usually two submedial tubercles and a tubercle at each humeral angle. Micropterous individuals are more common, although macropterous forms do exist. Macroptery is more common in males than females.

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