Popis: Analysis of head-capsule widths of field-collected and laboratory-hatched Sitona discoideus Gyllenhal larvae confirmed that this species possesses five larval instars. Probit analysis allowed for more accurate statistical definition of the head-capsule size ranges of each particular instar, despite size overlap between successive instars.
