Bamboo internodes pierced by weevils, the larval habitats of Sabethes identicus in nature.
Females of Rhinastus sternicornis perforating bamboos while mating (A) or lonely (B, C). A bamboo internode displaying three roughly linear series perforations (D) in a bamboo grove in the Atlantic Forest fragment at Bom Jardim da Roça, Duas Barras county, Rio de Janeiro, Brazil.

Mean number of Sabethes identicus females that took a blood at seven day intervals (P1 to P7) throughout their lifetime.
Table 3.
Estimated average ratio of number of eggs laid by Sabethes identicus in bamboos containing three types of liquid as choices for oviposition: Rearing water (RW), dechlorinate water with yeast (YW) and only dechlorinate water (DW), considering multilevel modeling.

Number of laid eggs and blood fed females of Sabethes identicus over their lifetime.
On the abscissa (x-axis), the cardinal and ordinal numbers refer respectively to the blood meal taken by the females and the number of days elapsed from their emergence from pupa.

Frames taken from Sabethes identicus gravid female laying egg in the laboratory, filmed at 3200 frames per second.
The recording illustrates the body and leg positions assumed before (A) and during (C) egg-throwing into the bamboo internode cavity through a tiny perforation drilled by a weevil. The arrows highlight the egg still held at the abdomen tip (A, B) and traveling toward the perforation in the bamboo internode (B). Some females probably missed the lumen of the aperture and the egg failed to reach the internode cavity. The eggs are stuck in the edge of the hole (D).
