The range of T. gerstaeckeri is from the south-western United States (New Mexico, Texas) to north-eastern Mexico. T. gerstaeckeri goes through three stages during its paurometabolous life cycle: egg, nymphal instars and adult.
T. gerstaeckeri is between 20 and 30 mm long when fully developed. It is all black except for their yellow horizontal lines outside of the pronotum. The tip of its mouthparts have hairs, but the rest of the mouthparts do not. T. gerstaeckeri have long, narrow legs and a flat head.

It has black forewings that cover the abdomen; the base of these forewings are yellowish orange.
T. gerstaeckeri is mostly found in the dry climates of northern Mexico, southern/central Texas and New Mexico where there is a lot of scrubby vegetation. Other Triatoma species are found throughout the... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Triatoma gerstaeckeri is recorded against all the insects logged in San Antonio (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
