Exuvia

This paper summarises the identification of all the Urothemistinae found in the Arabian Peninsula and provides a detailed description of the exuvia /final instar larva of U.

Other material examined: Bistriopelma sp., female from Peru, Ayacucho (RKCP 0701, exuvia); Euathlus truculentus Ausserer 1875, male holotype (BMNH 1590); Euathlus sp., male from Chile, between Santiago de Chile and Valparaiso (RKCP 0293); Phrixotrichus vulpinus Karsch 1880, male and female from Chile (RKCP 0066, 0067).

El dano por alimentacion sobre las ninfas del psilido fue reconocible por su completa deshidratacion, lo que se asemeja a una exuvia ninfal.

benjamina, las escamas del adulto son rectas y convexas de color negro brillante a opaco, con la exuvia marginal y amarilla.

Despues de cada exposicion, se anoto el numero de ninfas de las que se habia alimentado el parasitoide, reconocibles por la forma de V invertida que adoptan sin contenido de hemolinfa en su cuerpo, lo que las asemeja a una exuvia ninfal.

Uma apresentava abdome com pequenas cerdas e foi identificada como Chrysoperla externa, enquanto que a outra, com cerdas longas no abdome que permitem reter restos de exuvia, foi identificada como Ceraeochrysa sp.

There are a number of differences between modern scorpion molts and carcasses, such as the presence of internal organs in carcasses and the lack of most of these structures in exuvia, but differences based on internal anatomy are not readily apparent in fossils; indeed, internal structures usually cannot be discerned in fossil scorpions (but see: Wills 1925, 1946, 1960; Kjellesvig-Waering 1986).

These authors pointed out that exoskeleton material was derived from the ingestion of exuvia, rejecting the possibility of cannibalism of newly molted individuals.

Analyses of the FTIR spectra of the mineralized cuticle during intermolt and premolt and of the exuvia (Fig.

where, C is the energy consumed in food; G, the energy deposited for growth; F, the energy lost in feces, U, the energy in excretion; E, the energy spent for exuvia, and R, the energy for respiration.

Furthermore, adult chironomids were commonly observed during warm winter days (i.e., in December and January), and Soponis (1980, 1983) reported that pupal exuvia comprised more than half of the chironomids drifting in a north Florida stream in February when water temperatures were [approximately]12 [degrees] C.

Posteriormente, a partir de procesos hormonales, se separa el dermatoesqueleto (exuvia), transformandose la larva en un individuo adulto alado (Esquivel, 2006; Raebel, Merckx, Riordan, Macdonald, & Thompson, 2010).
