[The existance of a winter diapause revealed by the effects of hormone treatment in the spider Pisaura mirabilis Cl. (Pisauridae)].
In the same experimental conditions, injections of ecdysterone induce moulting phenomena appearing after significantly different times according to whether the nymphs of Pisaura have been captured in October or January. The variable sensibility of the spiders towards an equal amount of hormones allows us to confirm the occurrence of winter-diapause in this Arachnid.
