COURTSHIP BEHAVIOR AND LIFE CYCLE OF THE WOLF SPIDER SCHIZOCOSA MCCOOKI (ARANEAE, LYCOSIDAE)

Individuals of Schizocosa mccooki (Montgomery) are found in open areas of pinyon-juniper woodland in New Mexico. They co-occur with individuals of Alopecosa kochi (Keyserling) and Lycosa coloradensis Banks. Individuals of S. mccooki overwinter as immatures. They then mature in May, and mating occurs in May and June. During courtship, a male S. mccooki will make a quick jump, assume a position facing the female, and perform a series of palpal movements. The pattern of sound production includes a series of 2-18 bursts of percussion, with each burst consisting of 2-4 individual taps of the palps. The sounds produced from a courtship sequence of two individuals from Saskatchewan, Canada, were very similar to the sounds produced by the individuals from New Mexico.
