Haplaxius crudus (Van Duzee, 1907) - (American palm cixiid)
This plant hopper is found in Central America and is a vector of the lethal yellowing disease of coconut palms. However, the feeding activities do not leave any visible damage.
The adults are around 4-5 mm long and feed on the leaves of palm trees while nymphs develop on the roots of grasses. The average development period of nymphs is around 2-3 months, during which time they pass through 5 instars.
