Life Cycle
Grubs bore through the inside of the host plant, then pupate in a fibrous pupal case. Adults emerge from the plant and live for up to 60 days, looking for new hosts in which to lay their eggs.
A serious pest of tropical ornamentals, sugar cane and bananas, though its biggest impact may be leaving the plants susceptible to the Palmetto Weevil (Rhynchophorus cruentus). Larvae are hidden inside the plant and may be spread through nursery stock.
earliest record in our area: FL 1984[cite:185010]

the population in Florida belongs to the form sericeus, which by a recent molecular study(1), deserves species rank
