Rhizophora root borer
Coccotrypes rhizophorae
Family Scolytidae

Adult size:
2.6 mm

This beetle attacks the tips of young prop roots of Rhizophora, causing the plant to replace it by producing one of more lateral roots.

A heavily infested plant has a characteristic "stepped" look.

A sister species, C. fallax, is a serious pest, boring into unhealthy propagules on the ground, and thus a major source of replanting failure.
