Life can be a risky proposition when you are relatively low on the food chain, like a damselfly. Some larger insects may hunt you down while you are flying—see my recent post called Predator that shows an Eastern Pondhawk dragonfly consuming a damselfly. Other creatures may try to trap you and then immobilize you.
Several times this past week during visits to Occoquan Bay National Wildlife Refuge I have encountered Black and Yellow Garden Orbweaver spiders (Argiope aurantia) that had captured a damselfly. I did not see the actual capture, but the spider in the first photo was in the process of wrapping up the damselfly when I spotted.
Spiders can produce variety of types of silk. In cases like this, the silk (known as aciniform silk) comes out in sheets that look like a gauze bandage and the spider spins around the prey as it wraps it up. If you want to get a better look at how the spider emits these sheets of silk, check out a 2014 posting called Wrapping up a meal. If you have every wrapped presents at Christmas time, you know how difficult it is to wrap an irregularly shaped object. The spider has done an amazing job in making a compact package of the long skinny body and wings of the hapless damselfly—I encourage you to click on the image to see the details of the trapped damselfly.
In the case of the second photo, the spider was content to do a looser wrap, which lets us see the damselfly a little better. I think this damselfly and the one in the first photo are Big Bluets (Enallagma durum), though it is difficult to be certain of the identification.

I believe I can fly

This photo leaves me a little confused, because the larval shell to which this damselfly is clinging seems too big for its body and looks more like it belonged to a dragonfly.
There are plenty of places on the internet where you can read about the life cycle of dragonflies and damselflies, but the short version is that they spend most of their lives in the water as nymphs. There they go through a series of larval stages in which they shed their skin that has grown too tight. Just before they molt for the final time, they climb out of the water and, once the skin dries, the damselflies emerge. They then have to rest for a little while as their wings unfurl and their legs get stronger. Only then can they fly away.
This pretty little damselfly seems to be in the resting phase on a little rock ledge at the edge of a pond at a local garden. I wanted to try to get a bit closer, but the embankment where the ledge was located was steep and muddy and I would have had to be standing in the water to get a better angle.
I like the photo a lot and find it to be weirdly fascinating. The landscape is simple and rugged, with some texture in the foreground. The moulted shell still seems lifelike and seems to be looking at us with a slightly tilted head. The damselfly itself has the only color in the image and attracts the viewers’ eyes. There is a kind of tension in the damselfly’s pose, as it hangs on with all of its strength, waiting until the moment when it can fly away.
Imagine what it would be like waiting, waiting for the moment when you take to the air for the first time, leaving behind forever your old life in the water.
