Harmostes dorsalis
This record describes Harmostes dorsalis (species). Recorded family: Rhopalidae. Recorded order: Hemiptera.
Identification and Appearance

The following characters were gleaned from although not explicitly mentioned as being diagnostic or unique to H. dorsalis : Among the species of Harmostes found in the western United States ( angustatus , dorsalis , and reflexulus ), this species may be recognized by the finely punctate cells of the clavus and corium. This punctation is apparently finer than that of the pronotum and is only conspicuous near the hemelytral veins (or in other words, near the margins of the cells). Much more variable but also of potential value in identification is the reddish tinge (transl. carmine red) of the hemelytra with the lighter costal margin; presumably this is the character from which the epithet subrufus derived (drswanny, Jun 2012).

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