Water Measurer
A very slender, elongate semi-aquatic bug that walks slowly on water surfaces in the Americas. Its head is exceptionally long and narrow with a small rostrum at the tip. It moves with slow, deliberate steps along pond margins.
Did You Know?
It is so lightweight that it can walk on the water surface without breaking the surface tension, leaving no visible dimples where its feet contact the water.
Triatoma brasiliensis
The most important Chagas disease vector in the semi-arid Caatinga region of northeastern Brazil. It thrives in rocky outcrops and stone wall crevices.
Did You Know?
Its ability to colonize both natural rock habitats and human dwellings makes it extremely difficult to eradicate.
