Dragonflies, Damselflies and Spiders

I have taken a few pictures of spiders, so if you do not like spiders, I don't recommend my Bugs Gallery.

I recently found out the difference between a dragonfly and a damselfly. For a long time I thought damselflies were young dragonflies.
Dragonflies are typically larger than damselflies and when resting keep their wings out to the side or pointed forward. Damselflies keep their wings back along their bodies and their eyes are clearly separated.
