I soon was visited by a couple of red-bodied damselflies. (Damselflies are the thin-bodied ones). One of them kept coming back to the pond. She really seemed to like the Arrowhead plant Sagittaria. Eventually I was able to video her ovipositing. This is when she dips her abdomen in the water to deposit her eggs.
Damselfly and dragonfly start life in the water and grow through a large number of nymph stages. Depending on the species, and also environmental factors such as the temperature, they can stay up to four years in the water! Imagine my surprise when I was clearing out the blanket weed and came across this:

It's difficult to know what stage it's at, but already you can see those dragonfly eyes, and it's quite a predator! I put it back in the water to develop further.
I made sure my pond was planted with some reeds because the final stage nymphs climb out of the water and up the reeds, before they undergo their final metamorphosis into the flying form.
Well, I might have to wait a while before they emerge from my pond, but today when I was visiting my mother-in-law, I took the opportunity to check on some reeds that were in a community garden.
I found a nymph skin on one of the reeds. It was empty; it could have been long gone as they remain for quite a while. It is still amazing to look at the skin in detail and just imagine the miraculous reorganisation of the tissue that goes on inside there!
Can't wait to catch a dragonfly emerging from my own pond!
