Adult emergence extended from early May to early June. The sex ratio of emerging adults favored males by as much as 2.7:1. Oviposition occurred from mid-May to early June. Significantly more eggs per fascicle were deposited on the distal third of branches and in the lower third of the crown. Larval feeding took place throughout June. The proportion of prepupae remaining in the soil for more than 1 year varied from 9% to 66% between two sites. There was no evidence of egg parasitism, and egg survival exceeded 95% in each of 2 years. A new species of nematode (Steinernema sp.) (Nematoda: Steinernematidae) was recovered from pronymphs. Homaspis interruptus (Provancher) (Hymenoptera: Ichneumonidae) parasitized larvae and emerged from 8.5% and 2.8% of the pronymphs in two populations.
