Synonyms and other taxonomic changes
Odontota dorsalis (Thunberg)
Orig. Comb: Chalepus dorsalis Thunberg, 1805
Adult has overall orange-colored pronotum and elytra, with a widening black stripe along the elytra.
Species profile by E.G. Riley (1)

Perhaps a mimic of Lycids; compare:
e NA (LA-FL-QC-MB) (2)
Robinia pseudoacacia (Fabaceae) is an especially favored larval and adult host; also found on many other Fabaceae, incl. herbaceous spp. (3)
O. dorsalis lays eggs on leaf undersides in masses of 3-5, and a brown spot appears on the upper leaf surface above the egg mass. The larvae enter the leaf through one hole and together form a single blotch mine. On the other hand the lepidopteran mines on locust leaves have one larva per mine, and their legs are not as well developed as those of Odontota. (C. Eiseman).

O. horni is similar but the pale ground color is strongly reddish and the black sutural area of the elytra is much narrower.
