pheromone gland in a melolonthinae beetle, Holotrichia parallela.
This last mentioned genus is particular because according to HALL & HARVEY (2002: 185) it possesses specialized androconial organ: the abdominal coremata, which is a pair of eversible
tubes of membranous type only present in certain nymphalid subfamilies (Danainae, Satyrinae and Morphinae).
This accuracy could certainly be as a result of employing the paddle deflectors and highly flexible abdominal tip, but the muscular eversible
spray nozzle with hydrodynamic pores as shown here may serve to achieve accuracy.
Each capsule contains a folded, eversible
tubule containing a variety of toxins.
This may explain the r eversible
characteristics of physical gelation observed in EVA-organoclay systems.
Worms have been shown to apply these dorsoventral forces either by using an eversible
pharynx or proboscis (Dorganet al., 2007; Murphy and Dorgan, 2011) or by anterior expansions using their hydrostatic skeletons (Che and Dorgan, 2010).
In fact, asymmetry of the eversible
vesica is nearly universal in Lepidoptera (Chapman 1902) and appears associated with asymmetry in the female internal genitalia (Huber et al.
Species of Pyrgotomyia share the long antenna (pedicel and flagellomere 1 long), long oviscape, and eversible
membrane of the ovipositor with rudimentary (or without any) sclerotized structures, and I consider these characters to support monophyly of the genus.
The copulatory organ is a mass of richly vascularized tissue, with intense pigmentation from the base to the extremity of the penis, which is eversible
through the cloaca by the action of erector muscles and blood inflow.
At its basal end is a ventral basal lobe or eversible
sac, with small, conical, scale-like teeth covering part of its surface (Fig.
