Watch its gills pulse as it gathers oxygen from the water. Dobsonflies are sensitive to environmental conditions so their presence is an indicator of good water quality.

The dobsonfly’s journey begins when the adult female lays her eggs in a fast-moving stream or river. After emerging from the eggs, larvae, like the one you see here, will hide under rocks and in crevices until they morph into their final adult form. In its aquatic larvae phase, the dobsonfly is a fierce predator, equipped with sharp pincers capable of piercing human skin.

I absolutely love dobsonflies!! This is a male dobsonfly, species Corydalus batesii. Found at @manu.biostation. You can tell he’s a male by his humongous mandibles. I have seen tons of misinformation online about these incredible insects, so I wanted to make it clear that these are not dangerous whatsoever.
