Biology.
Specimens from
Venezuela
were recorded from the bamboo
Phyllostachys
and a specimen from
Trinidad
was taken from felled bamboo. Specimens from
Ecuador
have been collected in numbers on felled and split culms of the bamboo
Guadua angustifolia
as well as in association with corn (
Zea
mais
) and
Inga
sp., and specimens from
Venezuela
and
Colombia
have also been found on corn. At
United States
border ports specimens have been intercepted in bamboo and bamboo slats as well as in banana.
Comments.
All specimens examined from
Ecuador
have the elytral humeral and the declivital areas with reddish maculations. No distinctions other that these color differences were noted in
E. setulosa
from elsewhere (including the male genitalia). The fully black specimens and those with red maculations are considered conspecific.
