The external egg morphology of the phyllopod species recorded in France is described by means of S.E.M. Differences in diameter and ornamentation of envelope are stressed. We propose a dichotomous key to allow the identification of species even when their biotope is dry. Results are compared with previous studies on Anostraca, Notostraca and Spinicaudata and their taxonomical value is discussed.
Cyprinid fish from the Lergue and Lez rivers in Herault, southern France, were found to be parasitized by the microsporidian Pleistophora mirandellae Vaney & Conte, 1901. The parasite was found only in the gonads, forming cysts in the connective tissue between the seminiferous tubules of testes or occurring in the oocytes of the ovaries. Two types of uninuclear spores are produced. The synonomy of mierosporidia parasitizing the gonads of cyprinid fish is discussed.

We present descriptions of the egg, the three larval instars, and the puparium, and also some information on the biology of Dichetophora obliterata, a strictly terrestrial Sciomyzidae (Diptera). This life cycle is the first that has been published for a species in this genus. We provide information on the flight period of adults, the duration of preoviposition and all immature stages, and the larval feeding behavior. By all these characteristics, D. obliterata (palearctic) is placed in phenologic group IV of Berg et al. (Berg, C. O., Foote, B. A., Knutson, L. V., Barnes, J. K., Arnold, S. L., and Valley, K. 1982. Mem. Entomol. Soc. Wash. 10: 15–36).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
