Odontota scapularis

Odontota scapularis (Olivier) (Figs. 19, 73–74, 147) Reared specimens. MASSACHUSETTS, Hampden Co., Wales, 42.09014789, -72.20011674, 10.viii.2017, em. 23.viii.2017, C.S. Eiseman, ex Apios americana, # CSE4174 (1 adult, ZFMK); NORTH CAROLINA: Scotland Co., Laurinburg, St. Andrews University, 2.vi.2015, em. late vi.2015, T. S. Feldman, ex Apios americana, # CSE2231 (3 adults, ZFMK). Other collected mines. NORTH CAROLINA: Scotland Co., Laurinburg, St. Andrews University, 15.v.2015, T. S. Feldman, Apios americana. Hosts. Fabaceae: Apios americana Medik. Adults have been reported from Desmodium Desv., Gleditsia triacanthos L., and various non-fabaceous plants (Ford & Cavey 1985; Clark et al. 2004), but there is no indication that any of these serve as larval hosts. Biology. The eggs (Fig. 19) and mine (Figs. 73–74) were described and illustrated by Eiseman (2014), and our new observations are consistent with the previous ones. As with Odontota horni on other hosts, the mine is puffy and full-depth with frass in scattered, small, elongate particles. The mature larvae are typically found in a different leaflet from the egg cluster. Parasitoids. An adult of Chrysocharis occidentalis (Girault) (Eulophidae) emerged from one of the mines collected on 15 May 2015 (CSE1599, BMNH). Eiseman (2014) observed a Closterocerus Westwood adult that had apparently just emerged from an egg of this beetle. Otherwise, an unspecified Sympiesis Fo ̈rster (Eulophidae) from an unspecified Odontota (Thompson 1954) is the only previous parasitoid record for a member of this genus other than O. dorsalis (Noyes 2020). Notes. Our Massachusetts specimen differs from the two barcoded North Carolina specimens by 0.62% and 0.92%, but by 2.15% from the only other member of BIN BOLD: ADF6942, a specimen of O. scapularis collected in Virginia.
