I have never been able to convince my kids that dragonflies are anything short of dangerous....
When I was a kid, dragonflies and ladybugs were the two kinds of bugs that we would never kill.

According to Wikipedia, O. pumilio, while not the most poisonous of the Dendrobatids, is the most toxic member of its genus.
Lucky for them that they are poisonous because they do look good enough to eat.

I wonder what the selective pressure is that favors bright colors in amphibians? Warning predators, competition for mates, or attracting mates, or maybe all of these?
There's a delicate balance between the ability to attract mates and the ability to evade predators. I suppose species that have the eyesight to appreciate bright colours also have an advantage in seeing the predators coming.

Re: Another dragonfly
The shadows of the wings? That's pretty impressive photography.

These 2 shots are not very good photographically....
Easy for you to say. All you have to do to get cheers is post your second-rate photos. The rest of us have to think up clever comments.
