Why the Name?
Glass worms are transparent – except for their tiny air
bladders that look like black dots. You
have a hard time seeing them except when they move in twitches.
And they are not really worms.
They are the larvae of a non-biting midge.
Origins: Glass worms grow wild in ponds, pools, and permanent puddles. You won’t see them in lakes with fish, because fish eat them. They are harvested in largest numbers from ice-covered lakes.
Appeal: Fish love the taste of glass worms – even the pickiest eaters. You might have a hard time seeing them, but your fishes spot them almost instantly. As they twitch and turn in the water, your fishes’ hunting instincts kick in. They want to rip and rend their prey. Bettas can stuff their guts to bursting if you over feed them. Most fish are smart enough to know when to quit.
Eating Size: Glass worms hit the market at 0.5 to 0.75 inches.. Their size makes them ideal for two to six-inch fish. Aggressive fish in the one-inch range such as puffers, young cichlids, and bumblebee gobies also avidly devour glass worms. One-inch feeder-size guppies will find them about an even match to wrestle with. If they grab a glass worm, the glass worm will usually jerk them around and escape from their greedy grasp. Baby guppies (and other fry) will be eaten by the carnivorous glass worms.
Adults. Looking very much like mosquitoes, the non-biting parents lay their eggs in the water and flit off to die. Adults live ten days. They look like mosquitoes but do not suck your blood. Some people call them phantom midges. If you pedal your bike along the river trail up to Saylorville, you may have noticed these midges. As the sun goes down on a hot summer evening, these midges (and mosquitoes) come out in mass quantities. If you ride shirtless, they will stick to your sweaty chest. Try not to breathe them. Although, they are nutritious.
Larvae: When the eggs hatch, the glass worm larvae start eating the various micro-organisms (as well as baby fish) that live in their aquatic universe. They must take longer to mature than mosquitoes which pupate and flit off in 10 days., because they over winter under the ice.
You can find small quantities of glass worms in shaded ponds during
the non-winter months. However,
massive quantities of glass worms come out of states with colder and
longer winters than we enjoy in
Containers: We keep our glass worms in several shallow un-aerated plastic tubs. They hold one or two inches of nearly solid glass worms. You can keep small quantities in any container. They will last (unfed) for at least a month.
Chaoborus larvae (probably not the same species) abound in the
Glass worms make an excellent menu item for picky eaters and
potential breeders. LA.
