http://www.fcps.edu/islandcreekes/ecology/green_darner.htm . How can I become so enthralled about a dead insect? Maybe because it's wings look like gossamer. ( I heard that word somewhere and I think it sounds good and I wanted to use it!!) The wing span is 4" and the body from head to end of tail is 3". God did a really good job on this one!!Nope, a Common Green Darner is not a darning needle, it's a Dragonfly and I have one and I like dragonflies!! Period....A friend found this Common Green Darner in her yard and it was dead so she gave it to me..It really is a pretty dragonfly, although probably not the cream of the crop. There are many out there that have more beautiful colors on them. My CGD is a female, I'm pretty sure after looking at the pictures on the following site. I found out a lot on the Common Green Darner on this site and they have awesome pictures too. You can click here if you want to know more about them.
