    Fishfly - (Chauliodes pectinicornis.)

    A Fishfly doesn't eat fish, but the small aquatic insects and plant matter that reside in water.

    Staff Writer (1/15/2014): Fishflies are part of the Alderfly and Dobsonfly group of winged insects. They are generally noticed for their large size, color and seemingly uncoordinated flight approach. They have jaws (mandibles) that have saw-like teeth and long feathery antennae. Their wings are as long, or longer than, their bodies and fold tightly, one-over-the-other, when closed. Veins on the wings cover the wings as well as splotches of coloration.

    Males use their jaws to fight over females. Females lay hundreds of fertilized eggs above the water on low-hanging branches or plants. Larvae hatch and drop into the water. They are found hanging around vegetation near moving water, while adults can be found resting on dwellings nearby.

    Activity is mostly seen at night during the late spring and throughout the summer. Adult Fishflies pull aquatic insects (naiads of dragonflies, water beetles, etc,) out of the water and eat them. They will also eat worms, small bivalves (clams, mussels) and algae. Adults are very drawn to lights at night.

    BUGFINDER: What Kind of Bug is This...
    BUGFINDER allows for a quick search of the Insect Identification database by selecting primary color, secondary color, number of legs and the territory / state in question. If only one color is present on your insect, select it again as its SECONDARY color. Remember that the more details you can offer, the better your chances of finding a match. As a rule of thumb, six legs are typical for most insects whereas spiders generally have eight legs.
