Egg morphology
Chorion opaque white.

Egg mass pattern:
Winged females use their long ovipositor to lay eggs in crevices, usually some distance from the pupation site. Apterous females with functional legs stay on their bag upon mating and insert their telescopic abdomen into the lower opening of the bag to oviposit in their pupal case. In species with vermiform females that remain inside their pupal case, peristaltic contractions of the abdomen allow females to discharge their eggs intermixed with abdominal setae inside the upper section of their pupal case, progressively shrinking in the process (Rhainids et al, in press).
Description of egg morphology:
Egg of Perisceptis carnivora Davis 0.45-0.5 mm in length, maximum diameter ~ 0.35 mm, superficially similar to that described for Brachycyttarus griseus De Joannis (Davis 1990). Micropyle consisting of an irregularly circular central disk ~ 8-13 �m in diameter with 11-13 low, slender ridges radiating outwards; arms occasionally branching, sometimes joining adjacent ridges to form a few closed cells. Each egg (only for Perisceptis carnivora) enclosed within a firmly woven, golden cocoon spun from long, finely barbed setae derived from seventh abdominal segment of female; length of egg cocoon ~ 1.0 mm, width ~ 0.7 mm (Davis, et al 2008).
