The nesting behaviour of the solitary wasp Tachysphex inconspicuus (Kirby) was comparatively studied based on observations made in two environmentally distinct locations in southeast Brazil: upper portions of two sandy beaches and a dirt road in a forested area. Motor patterns related to nest construction were similar in all observed wasps, but some behavioural features, which were different among the observed wasps in the two environments, seem to be constrained by ecological factors. T. inconspicuus can be behaviourally differentiated from several other species of the genus by the following combination of features: they close the nest temporarily during its provision, do not let the excavated sand to form into a mound in front of the nest entrance,...

Aspects of the nesting behaviour of Sphex opacus Dahlbom, 1845 are presented for the first time, based on observations carried out in a coastal habitat from southeastern Brazil. Larval behaviour and development were studied in laboratorial conditions.

The last instar larva of Trypoxylon (Trypargilum) albitarse Fabricius, 1804 is described and illustrated, based on one specimen collected in southeastern Brazil. This larva can be distinguished from other described larvae of the subgenus Trypargilum Richards, 1934 for the following combination of features: integument of the body with spines; labrum and epipharynx with sensillae; medio-apical and latero-basal portions of the epipharynx devoid of spines.

Nesting behaviour and larval biology of Prionyx fervens (Linnaeus) (Hymenoptera, Sphecidae) from Brazil

The nesting behaviour of Prionyx fervens (Linnaeus, 1758) is described, based on one nesting female observed in a coastal environment from southeastern Brazil. One prey bearing a wasp's egg was created in laboratorial conditions and aspects of the larval behaviour and development are described. Schistocerca cancellata (Serville, 1838) (Caelifera, Acrididae) was found as prey.

Description of the last instar larva of Tachysphex inconspicuus (Kirby) (Hymenoptera, Crabronidae) from Brazil

The last instar larva of Tachysphex inconspicuus (Kirby, 1890) is described and illustrated. Minute spines on the anterior dorsal annulets of abdominal segments and different types of setae on prothorax and mesothorax are remarkable features observed in the larva of T. inconspicuus which were not reported in previously descriptions of larvae of the genus. Distribution of spines and sensilla on the epipharynx and distribution of setae on head and body seem also useful to distinguish Tachysphex larvae.
