Excerpt from The Snowy Tree Cricket and Other Insects Injurious to Raspberries

The adults lay small round eggs on the debris collected about the bases of the canes. These eggs are at first opaque-white, but soon turn a light brown. Specimens kept in the laboratory began ovipositing on J une 18. Oviposition was continued steadily by some of the speci mens until October 8. During this time isolated females laid 243, 296, 390, 502, and 562 eggs, respectively, averaging eggs each. Four females which laid throughout the entire period (four and one-half months) laid on the average eggs a day. The highest number of eggs laid in one day was 15.

Eggs hatched in the laboratory from 7 to 20 days after being laid, with the majority hatching from 9 to 14 days after being deposited.
