Species mozardi (Clover Stem Borer)
Explanation of Names
Languria mozardi Latreille 1807
4-9 mm(1) (mostly 5-7 mm)
Antennal club emerging gradually from stem, seventh segment (base of club) less than twice as wide as preceding segments, segments only slightly dilated to inner side; head red; thorax spotless; abdomen with last three (sometimes last two, rarely just one) ventrites piceous(1)
e. NA to AZ (QC-MB to FL-AZ) / n. Mex. - Map (1)(2)(3)(4)(5)
Feb-Nov(1), but mostly Mar-July (5)
polyphagous, but mostly hosts on Asteraceae(1), infests red clover in the southeast and alfalfa in the southwest(1), and, potentially, canola (Ward et al. 2007.)
Life Cycle
larvae and pupae in stems of dozens of plants spp. in at least 6 families(1)
most common and widespread of our languriines(1)

told from discoidea by the lack of the median dark spot on the thorax, by the shining, not alutaceous, thorax and elytra, and generally smaller size;
from denticulata by the smooth, not sinuate, elytral apices and by the presence of more than one piceous abdominal segment;
from californica by the lack of all piceous abdomen and by the shallower punctuation on the under surface, especially on the metasternum;
from laeta by the gradual, not abrupt, emergence of the antennal club from the stem, by the lack of all piceous abdomen, and by smaller size.(1)
