Development to diapause in a population of <i>Euphydryas gillettii</i> (Nymphalidae): effects of egg cluster size and habitat parameters
Abstract
I studied survivorship from the period of egg laying to winter diapause in a population of E. gillettii (Nymphalidae). I investigated if fitness, in the context of hatching and succesful development to diapause was related to egg cluster size, habitat parameters, or both, and if there were factors affecting egg cluster size. Results indicate that hatching is affected by sun exoposure of the egg cluster and predation risk and soil condition of the host plant. Egg cluster size had no affect hatching. This suggests that there is no optimal cluster size that increases fitness of the eggs; clusters are susceptible to equal amounts of mortality regardless of their size. Post-hatching fitness remains to be determined. Egg cluster size was related to its sun exposure and the number of egg layers in the cluster. Faster development occured for egg masses laid in one layer on plants with a low predation risk and dry soil conditions.
