Observations on the seasonal occurrence and egg production of the grasshopper Chorthippus curtipennis Harris (Insecta: Orthoptera) in Newfoundland

Abstract

Grasshoppers, Chorthippus curtipennis Harris, were collected on grassy hillsides and in sphagnum bog near St. John's during the summer of 1969. Dissections of females showed that the usual number of ovarioles was four in each ovary, that oviposition was restricted effectively to the last week of August and the first 2 weeks of September, and that grasshoppers from the bog were more heavily parasitized by calliphorid larvae than those from the hillsides.
