Did you know that Dragonflies are a big deal to creeks?  Did you know that there is a dragonfly cycle? So first the dragonflies eat the weta, then the dragonfly gets eaten by the eel and then the eel reproduces the water.

When was the last time you saw a dragonfly? Nowhere days you don’t see dragonflies, it’s like they disappeared. You use to see them at creeks but you don’t. Well dragonflies have not been seen at creek because the creek might have been  polluted.

Dragonflies have big eyes which means if a predator tries to catch them, then they can see them coming. Dragonflies have over a hundred eyes. Dragonflies haves many family relatives like Beetles and mosquitoes.
