    WoW! You should really print those out! It's a photo-essay of the emmergence! That is really cool. I would not say that was time wasted at all. Very impressive photography....and patience!

    That's very awesome! Asside from mantids, odonates are a second favorite insect. They're very diffcult to preserve like a butterfly-only more delicate!

    How is it that you came across a damselfly larvae in your fishtank? Are there fish in it? Are the tanks outside or how did it lay an egg in the aquuarium and without the fishes having a snack.

    I'd love to hear how this critter came about!

    Thanks for all the comments!

    Schloaty: I might do that, but I will probably have to get a full sequence first. As most of them have already emerged(I can't find anymore larvae), maybe next year. I may also try a dragonfly too. I always thought I was an impatient person.

    Swords: No where near as exciting as your thoughts were but here it is anyway.

    ...I have an extra ten gallon that is usually breeding fish and raising fry. It was not in service for most of the summer, so it served as a "treat holder". Here, any damselflies, mosquito larvae, and other critters that I came across during pond replanting and other tasks waited until they were fed to a fish, newt, etc. The damselfly probably helped itself to lots of the mozzie larvae while he stayed in there.

    Apparently, this guy was missed, and I spotted him crawling up a corner that day.

    I see! That's an awesome idea, a treat aquarium for harvested bugs! I've raised fish (killifish mostly) for a lot of years but never thought of setting up a seperate aquarium for wild water bug foods! I had a small fish bowl /series of bottles for hatching/raising brine shrimp for killi fry but never used outdoor bugs.

    Those guys would be great to have in a tank just for observing emergences! Do you know if the damselfly larvae are cannibalistic against their kin or can you keep a bunch in one tank-maybe if they have lots of aquatic plants and rocks to dart around in?
    I love the drastic difference between the appearance of the larvae and final flying dragon/damsel fly. Unlike Maggots and grubs the immature forms of insects, the odonates are just as cool looking as the adults! How long did you have the larvae before the emergence that you photographed?

    Be sure to post any other future cool experiments like this, I know I'd love reading them!

    I heard somewhere that odonate larva take 2 years to mature before they moult.

    Truly amazing!

    Tell me, how long have you had your tank set up? with all the creatures in it, how do you mantain water quality and proper oxygen levles
    that makes no logic

    Swords: I've heard of lots of people go out to collect mosquito larvae for there fish. I myself couldn't stand watching all this "spontaneously generated" food swimming in the pond without using a bit for myself.

    I believe he was in this tank for at least 1 month, possibly more. I go mainly for the small ones for the fish as the only animal I have that can down fully grown larvae is the newt.

    I've also thought of setting up a little larvae tank too. That would be awesome. I remember when I was very young I kept some dragonfly larvae in an upsidedown frisbee and fed them baby mosquitofish...who had difficulty evading the constant ambushes due to shallow water. In fact, right now a dragonfly skin is still clutching a power cord into my ten gallon upstairs tank. This guy emerged while we were on a trip...and a beautiful darner dragonfly was resting in the windowsill when I arrived. He probably either escaped being eaten, or snuck in with the plants. If you want, I have some dragonfly larvae pictures that I took...showing the protruding mask(I pulled it forward for the shots...you can see the little teeth inside).

    Finch: I'm not sure, but I'm going to guess that the species in my pond take 1 year. In winter, when you dredge up pots or pull muck from the bottom(I also collect scuds...managed to start a culture from the ones in the pond) you get lots of 1 inch or so larvae. All are pretty similar in size. And since right now I can't find any, I think its a once a year thing.

    Dragonfly and damselfly larvae could care less about how clean the tank is kept-they are quite hardy. However, I usually do water changes on my tanks at least 2 times a week...depending on how much time I have. I use a 3 gallon bucket, so the result is about a 20 percent water change on the 46 gallon bowfront(which houses my fish). Though some aquarists use air pumps to agitate the water surface and add more oxygen, the filter does that just fine for me.

    The 46 gallon has been up with fish in it for 4 years...though a major revamp took place this winter...not finished yet if you check the freshwater board here for pics. My ten gallon upstairs tank is about 1 year old and houses a colony of Heterandria formosa and a single lonely Chinese firebelly newt.
