My Research Video

Posted by David Moskowitz on October 3, 2009 at 4:21 PM

The Entomological Society of America is holding a video competition for members and the videos are posted on Youtube http://www.youtube.com/profile?user=entsoc&view=videos


There are some really fantastic videos of amazing insects and people. I entered a 2 minute video about my research on Cordulegaster erronea http://www.youtube.com/watch?v=cMPru3zihmQ&feature=channel_page and what I have been able to tease from this really interesting and enigmatic species over the past few years. It is one of the coolest dragonflies and only occurs on really beautiful, small, rocky, cold, clean, shady forested streams. Really not bad for a study area!


I've been conducting a wide variety of investigations to try and glean information about its life history including radio-tracking, larval surveying, mark-resighting and simulating mate behavior. The ecology of the Tiger spiketail and other cordulids, is generally poorly known but may offer insight into mate recognition and mating systems.


The males patrol the streams for long-periods of time searching for ovipositing females. Through my research, I have been gaining an understanding of mate recognition triggers. It is likely that the males recognize the ovipositing posture and movement of the females and that their movement pattern, color and shape are critical mechanisms for males recognizing females. I was lucky to capture two mating instances (actually pre-copulation activities) and capture them on film. The information about what happened is on the video page at http://members.webs.com/MembersB/editAppPage.jsp?app=videos&path=%2F#videos/videos/view/5202703-mate-recognition-and-mating-behavior-in-cordulegaster-erronea-the-tiger-spiketail-dragonfly-
