Abstract

Wolf spider females have the distinctive behaviour of carrying the egg sac attached to the spinnerets. If this egg sac is dislodged, the female will retrieve and reattach it, if possible. However, in some instances, a female may reattach another object of similar size or shape as a replacement for a lost egg sac. Here, I report the first example of an isopod, Armadillidium vulgare, being used as a substitute for a missing egg sac in Pardosa valensBarnes, 1959 from southeastern Arizona.
