Predictably, though, they fell by the wayside and other sorts of databases took their place. In like fashion, I worry that much of what we do today will soon vanish into electronic limbo, disappear off the web, or exist only in files that are incompatible 48 damselflies of alberta with the latest software.

Unlike the adults, larvae can be kept quite easily in aquariums, and fed on small live food items, the way one feeds the fussy species of tropical fishes (with brine shrimp, black worms, Daphnia, and so on—ask about these foods at specialty aquarium shops). If you give your damselfly larvae sticks or plant stems to crawl out on (as well as underwater sticks or vegetation so they can establish individual hunting territories), they may emerge as adults for you. It is important here, however, that you make sure that their maiden flight does not end in a collision with the lid of the aquarium, and a drowning death back in the water.
