I released my third of the season - all males. The mortality rate seems very high so far this year. Larvae are turning black or brown through 3rd instar and over half that have formed "J"s die within several hour. One chrysalis had tachinid threads hanging from it this am and one chrysalis left outside was parasitized by a spider. This spring has been unusually wet with wide ranges in temperatures -- perhaps factors?
