Genus Zabrotes
Explanation of Names
Zabrotes Horn 1885
Numbers
18 spp. in our area(1)
Size
Most 1.0-2.5 mm, 1 sp. (amplissimus) reaches 3.7 mm (1)
Range
Mostly sw. US, but 2 spp. (Z. arenarius & Z. subnitens) range east to NJ-FL, two more (Z. densus & Z. spectabilis) north to OR, and Z. subfasciatus is tropicopolitan (reportedly established in TX)(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.(1)
Remarks
Our only representative of the subtribe Spermophagina Borowiec 1987
