Posts Tagged ‘Eastern Skunk Cabbage’

I was thrilled on Thursday to spot several Gray Petaltail dragonflies (Tachopteryx thoreyi) while I was exploring a small local pond. Actually I was exploring a mucky seep area beyond the pond, a habitat that I knew was preferred by this species. When I find an area with a lot of skunk cabbage, I know I am in the right kind of place to find this species.

Gray Petaltails are amazing. They are the only member of the monotypic genus Tachopteryx and are often considered to be the most primitive living odonates. Colorwise, they are mostly grey and black, which allows them to blend in perfectly with the bark of tree trunks on which they often perch.

The first photo below shows an almost perfectly camouflaged Gray Petaltail. I watched it land on the tree trunk and still had some difficulty finding it in my camera’s viewfinder. I carefully moved to the side a bit and captured the second image in which you can see the dragonfly a bit better.

Once I had spotted my first Gray Petaltail, I hung around the seep area for quite a while and had a number of additional encounters. The third photo shows a Gray Petaltail perching on a broken off tree in the distance and I really like the way that the background looks in the shot.

The final two shots are among my favorites, because they show a Gray Petaltail perched horizontally on skunk cabbage leaves. I have often tried to get shots like these, but in the past the Gray Petaltails have rarely perched on this vegetation. In the final image the dragonfly looks like it is perched vertically, but I took the shot with my camera pointed downward at the Gray Petaltail that was perched horizontally on the skunk cabbage leaf. I love the way I was able to capture the texture of the leaf and the shadows of the wings was a nice bonus.

Not all plants wait for the spring to start growing. Skunk cabbage (Symplocarpus foetid) starts growing in the winter and can generate its own heat and even melt snow around it when the ground is frozen. According to Wikipedia, skunk cabbage “is notable for its ability to generate temperatures of up to 27–63 °F (15–35 °C) above air temperature by cyanide resistant cellular respiration in order to melt its way through frozen ground, placing it among a small group of thermogenic plants.” I spotted these skunk cabbage plants this past Saturday at Occoquan Regional Park.

So why am I interested in this plant? Several types of dragonflies, including the Arrowhead Spiketail dragonfly and the Gray Petaltail dragonfly can be found in the kind of forest seeps where skunk cabbage grows. I am conducting advance reconnaissance of locations to explore when dragonfly season finally arrives. Last year I spotted my first dragonflies in early April, so I have “only” three months to wait for the opening of the 2021 dragonfly season.
