Description of immature stages of Ligyrus nasutus (Burmeister, 1847) (Coleoptera: Melolonthidae: Dynastinae) with information on its biology. Acta Zool. Mex [online]. 2010, vol.26, n.3, pp.617-625. ISSN 2448-8445.

The third instar larva of Ligyrus nasutus Burmeister is described based on five specimens collected from agricultural fields, where cattle fed with stubble from the previous cycle, and pastures with cattle in Villa Flores, Chiapas, Mexico. The pupa of L. nasutus is also described using specimens obtained from rearing in captivity. Drawings of the diagnostic structures, biological data and a key to the known larvae of the species of Ligyrus are included.
