RODRIGUEZ-MIRON, Geovanni M.  and  LOPEZ-PEREZ, Sara. Description of immature stages of Enagria ovata (Coleoptera: Chrysomelidae) and biological notes. Rev. Mex. Biodiv. [online]. 2017, vol.88, n.2, pp.300-306. ISSN 2007-8706.  https://doi.org/10.1016/j.rmb.2017.03.010.

Here we describe the first and the last immature stages and the pupa of Enagria ovata (Boheman, 1854). After a comparison between the first and last stages of E. ovata with those of Asteriza flavicornis (Olivier, 1790), Cistudinella obducta (Boheman, 1854) and Physonota alutacea Boheman, 1854, belonging to the Ischyrosonychini, we found differences in the number of scoli and teeth in the mandible. The pupa is different from that of A. flavicornis because of the absence of 2 processes in the anterior border of pronotum. Enagria ovata is present in the field from end of May to early November. Females laid 25-35 eggs, larvae hatch after 9-10 days and have 6 stages in a period of 22 days. Larvae and adults were observed on Montanoa tomentosa Cervant (Asteraceae).
