Many arachnids like other terrestrial arthropods, provide extensive maternal care. Few studies have quantified the underlying physiological costs of maternal care. We investigated how maternal care affects the free-moving wolf spider’s (Pardosa saltans) energy requirements. We described in detail their basic reproduction biology (i.e. carrying cocoon and young) and we evaluated the variation in the...
Wolf spiders’ (Lycosidae) maternal behaviour includes a specific phase called “egg brooding” which consists of guarding and carrying an egg-sac throughout the incubation period. The transport of an egg-sac can restrict mothers’ exploratory and locomotor activity, in particular when foraging. The present study details the ontogeny of maternal behaviour and assesses the influence of age of egg-sac (or...
