Having seen Jeremy's blog yesterday I was determined to get some more photographs of the dragonfly larvae in the pond.
This is a common darter:
I found two in the pond this morning.
It looks like all the broad-bodied chasers have emerged because I couldn't find any larvae today. The photo below was taken in June:
I wonder why they are so muddy compared with the darters. When they emerge from the pond they aren't muddy - maybe it's a method of avoiding predators?
I photographed this larva in August 2008. I suspect it's either an emperor dragonfly or a southern hawker.
