The true bug was first detected in California in 2008 and has spread to Arizona and New Mexico, according to a University of Florida announcement.
Mature adults are less than 1/4 inch long and are orange and black. They may be confused with immature harlequin bugs or adult multi-colored ladybird beetles.
The pest has yet to be found in Florida, but it's only a matter of time, entomologists say.
The pest has caused about 25 percent damage to cole crops in conventional fields in Arizona and almost 50 percent in organic fields.
