The larva of C. leguminicola is undescribed. Imagines have been bred from L. polyphyllus, and it is assumed that the larvae are eating the roots or stems of this plant. At present time we have no observations of the egg laying behaviour of females, but on one occasion two eggs and a first instar larva of a dipteran species were found under the most basal leaves of a Lupinus plant, and these are presumably C. leguminicola
