Reproductive behaviour and laying eggs in laboratory conditions. The abdomen of both sexes in ventral view has three distinct forms: very inflated, slightly convex and slightly concave ("hollow" form). In the laboratory, only females with inflated and convex abdomens lay eggs. These two abdominal forms widely predominate among individuals captured during the raining season. The slightly concave abdomen occurs more frequently during the dry season and accounts for up to 30% of collected flies, which may represent sexually immature individuals, those in quiescence (?), or females at the end of the laying period. In nature, as well as in the laboratory, females lay eggs on emerged leaves in lines of 2 to

larvae are carried passively by water movements or swim on the surface by their own means. In many instances, larvae were found in nature swimming beneath the water surface with their posterior spiracular disk in direct contact with the air. Larvae moved either by crawling on the water surface or swimming against the slow currents of the water. In the latter case, the larvae contracts the anterior end, then swiftly extended themselves, and then alternately swung their posterior end from right to left and vice-versa. These movements often result in encounters with vegetal fragments and among them, oligochaete prey hidden inside their sheltering vegetal tubes. We did not enumerate the prey density, though it seems high in comparison with the number of snail-predating living sciomyzid larva and fly adults collected in all stations.

Once in contact with a prey’s tube, the larva attacked quickly stretching over the tube and searching for the anterior orifice to attack the oligochaete worm inside. When the annelid was touched by the larva, it rapidly retracted into the tube; the larva followed it, and progressively crawled into the tube while consuming the worm. The posterior disk of the larva was always extruded outside the tube (

The embryonic period was very short with hatching occurring two days after being laid. First instar larvae moulted into second instars after 2 or 3 days. The second instar lasts 2–3 days, the third instar 4–6 days and the puparial period 5–6 days. Thus, the cycle is very rapid and reflects in accordance with the multivoltine character of

the shape of sensilla and their setting on the segments allow differentiation of each tagma. However, for the first time we suggest an explanation concerning their distribution on the last abdominal segment (Ab8), which is distinct from the other segments by the presence of peripherical lobes. On the preanal lobe are sensilla resulting from coalescence of both ventral tubercles n°2 and 3; on lateral tubercle is the sensillum resulting from ventral tubercle n°1. Other sensilla are dispatched on the four lobes placed around the peripherical disc. Particularly, each ventrolateral lobe supports the maximum of sensilla, four here. In species having five peripherical lobes, additional dorsolateral lobes each bears one sensillum and ventrolateral lobe only three. Also, can be noted a rearrangement on the segment Ab7 where sensillum n° 9 gets closer to sensillum n° 8. In any case, from actual results, the number of 11 pair’s sensilla seems to be constant on each thoracic and abdominal segment for all studied species of sciomyzid larvae.
