Map(2), but 2 spp. (
Z. arenarius & Z. subnitens) range east to NJ-FL, two more (
Z. densus & Z. spectabilis) north to OR, and

(1)Food
Larval host plants are known for only a few
Zabrotes species, and those are from genera like
Phaseolus, Senna, Cassia, Vicia and
Rhynchosia...all in the Pea Family (Fabaceae). Adults have been seen on and swept from flowers & foliage of plants from many diverse families, but the associations are often incidental and not necessarily indicative of a larval host relationship.
(1)Life Cycle
The larvae consume host plant seed, within which they live.
