Despite a general ignorance about invertebrate distribution, information is known about a number of species that are confined to threatened habitats of very limited extent in the Thompson-Okanagan valleys. In the late summer and fall, female Ground Mantids lay a small, rectangular egg mass about 7 mm long on the stems of low shrubs. The eggs overwinter and hatch about six or seven month later. A female may lay from three to six capsules of 50 to 400 eggs each. The nymphs mature in about 13 weeks.
Northern species have one brood and hibernate in the egg stage.
Male Ground Mantids have been recorded living up to 47 days and females up to 156 days. J. Entomol Soc. All rights reserved.
