Abstract

Philodromus praelustris Keyserling and P. cespiticolis Walckenaer have annual life cycles in the Niagara Peninsula. Females of P. praelustris produced up to 12 egg sacs containing a total of over 200 eggs in an insectary but the later eggs did not hatch. Fecundity of females in the orchards appeared to be considerably lower.

There was no experimental evidence that P. praelustris disperses by ballooning though some very young individuals probably do so. All stages disperse by bridging, i.e., by casting an air-borne loop of web that catches on distant objects.

P. praelustris perceives prey by contact or, over very short distances, by vision. Two species of ants were rejected as prey.
