Bottom Line: Data on the morphology of the egg, mature larva (L3) and pupa of Squamapion elongatum (Germar, 1817) are presented.The development cycle of this species lasts 51-54 days: a 12-day egg period, a 30-day larval period, and a 12-day pupal period, on average.The larvae are attacked by parasitic hymenopterans of the superfamily Chalcidoidea.

ABSTRACT
Data on the morphology of the egg, mature larva (L3) and pupa of Squamapion elongatum (Germar, 1817) are presented. The development cycle of this species lasts 51-54 days: a 12-day egg period, a 30-day larval period, and a 12-day pupal period, on average. The larvae are attacked by parasitic hymenopterans of the superfamily Chalcidoidea.

Mentions: Head (Figures 2, 9, 10): Yellow-brown, oval, with clear frontal suture completely extended to mandibular joint. Epicranium: length ca. 0.72 mm, width ca. 0.56 mm. Endocarina (enc) long, extended to 2/3 the length of the frons. One pair of ocelli (oc). Antennae (at) with conical sensorium and 2 small spinose sensilla (Fig. 10). Clypeus with 1 pair of short setae (cls1). Frons with 5 pairs of setae (fs) – fs2 and fs5 longer, fs1, fs3 and fs4 much shorter, at the apex of the endocarina, fs2-4 near the epistoma, fs5 close to the antennae (Fig. 2). Epicranium with 2 pairs of lateral setae (les) – les1 short, les2 long, more than 3 times longer than les1.; 5 pairs of dorsal setae (des) – des1 very long, des2 and des5 a bit shorter and des3 and des4 much shorter; 4 pairs of minute posterior setae (pes) (in line with des2); 1 sensillum between epicranial suture and pes and another sensillum laterally to des1 and close to des2.
