I cannot positively identify this bug. I have found things similar to it online, but nothing quite like this…
I have an aquaponics system and the are thriving in my duckweed grow bed. When I drained the bed today these things came out like spiders from the rocks at the bottom of the growbed. When I put in the duckweed there were small things swimming in the water, I actually assumed they were frershwater shrimp, but now I m guessing they have grown and this is what I have. What is this? should I get rid of it? Should I keep it? Can I eat it?

Dear Nick,
This is the naiad or aquatic nymph of a Dragonfly, and it is considered a beneficial insect that will eat mosquitoes and other small creatures in your aquaponics system.  We imagine you can eat it if you wanted to try, though we don’t believe we have seen any references regarding Dragonfly naiads being relished by entomophages.

I have found about 50 of these crazy little bugs in my pool over the last two days and have no desire to swim with them. My best guess is that I can be rid of them by keeping the pool algae free, which has been a problem this summer. In the meantime, what is this bug that lives underwater, moves very slowly on land does not survive outside of the water, swims very quickly in trying to escape my net, and has my wife so freaked out she will not swim in the pool until they are gone?
Thank you,

Dear Gary,
This is the aquatic larva of a Dragonfly, commonly called a Naiad, a name shared with other aquatic larvae of flying insects.  We are very curious about your pool, which has algae as well as thriving aquatic insect life.  Do you not use chlorine or other pool chemicals?  Since Dragonfly Naiads are predatory, they need to eat other aquatic creatures, including the larvae of Mosquitoes, hence they are beneficial insects.  Dragonfly Naiads are not aggressive toward humans, and they will not hurt you or your wife.

This huge bug kept trying to fly into my window. It was green and yellow with 4 wings. It looked kind of like a dragon fly mixed with a horse fly. I only got a couple pictures while it landed. I really want to know what it is.

Green Darner

Green Darner

Dear Hunter,
This is an exciting posting for us.  This is a Dragonfly known as a Green Darner.  They are strong fliers and they migrate, and we seem to recall reading somewhere that they are sometimes attracted to lights at night, which causes us to speculate if they might also travel by night.
  Opinicon Natural History has a page entitled Observations of Dragonflies Visiting Lights at Night where it states:  “Dragonflies (order Odonata, suborder Anisoptera) and normally diurnal. However some dragonflies are active by night. This is particularly true of long distance migrants that travel over open water where they cannot roost so must continue to fly even after dark ….  Reports of nocturnal adult dragonfly activity appear to be relatively scarce, especially with regard to North American species.”

Can you tell me what kind of bug this is? It looks like a cross between a moth/dragonfly/horsefly. Thanks!

Damselfly

Damselfly

Hi Paul,
This is actually a Damselfly, and not a Dragonfly.  Both are in the same insect order Odonata, but the wings of Dragonflies lie flat while resting and the wings of Damselflies are held folded over the body.

Hi Katie,
We believe your mating Dragonflies are Tiger Spiketails,
