The Backstory: It was my good fortune to observe a controlled burn at Huntley Meadows Park on 14 January 2016. One of the target fields is located near the “accidental vernal pool,” my nickname for one of several vernal pools at the end of the Hike-Bike Trail. While I was in the neighborhood, I decided to look around for Autumn Meadowhawks in the hope of extending the state record late-date for dragonflies. Although I didn’t see any dragonflies, I spotted another Chinese Mantis egg case located near two other oothecae observed on 03 January.

Post Update: Several members of the BugGuide Facebook group confirmed that these are in fact mantis egg cases. Group member Beatriz Moisset identified the species as Chinese Mantis (Tenodera sinensis), as indicated by the distinctive roundish shape of the oothecae. Chinese Mantis is a non-native species.
