The camera is a Nikon Coolpix 2100 digital compact camera, nothing fancy. They dont make them anymore but you can get them for ~£60 on ebay, it was only £150 when I got it. Its macro mode is pretty good, everything about it is amazing for the price.. I guess a similar but newer model such as the coolpix 4600 would be just as good at macro but I can't be sure. Noted you as well as you asked.
Dragonflies serve a purpose ! Put the cats indoors !
I have tried to have dragonflies -or their relatives the damsel flies perch on my finger, but they are wary. Their wings have a curious dent or bunched area in the veins near the middle. This is peculiar to the dragonfly order (3 suborders, 5 families, one is a tropical transistional form).
