If your luck enough to have Dragonfly’s and Damselfly’s in your yard and garden remember they feed on other insects and are amazing to watch and they come in a staggering number of sizes and colors.
Two of the common names that you may hear people call Dragonfly’s and Damselfly’s are “mosquito hawk” and “snake doctor.” No matter what name you choose to call them they are a wonder to watch and one of the good bugs to have in your yard and garden.
Dragonfly nymphs are extremely fast swimmers and will eat just about anything that moves under the water surface and on. They have a hyper-thrust mechanism to give them the extra speed-boost when they are pursuing a critter that gives the dragonfly nymph a run for its money. For a quick burst of speed, they eject water from their anal opening to act like a jet propulsion system, which makes it a near impossible feat for the nymph dragonfly’s prey to even think of an escape.
Dragonfly nymphs, eat mosquito larvae, other aquatic insects and worms, and for a little variety even small aquatic vertebrates like tadpoles and small fish.
The adult dragonfly likes to eat gnats, mayflies, flies, mosquitoes and other small flying insects. They sometimes eat butterflies, moths and bees too. Adult dragonflies eat just about anything that is edible and can be caught. They keep mosquito populations under strict control by feasting on them when they are in abundance. Similarly, they also feed on ants, termites, butterflies, gnats, bees and other insects and tend to hunt in groups when large colonies of ants or termites are spotted.
Damselfly is an insect similar in appearance to the common dragonfly. Damselflies can be distinguished from dragonflies because their wings are held along their body when they are not in flight, as opposed to fanned out like a dragonfly’s wings. Damselflies also have segmented eyes and are generally smaller than dragonflies. Like the dragonfly, the damselfly’s diet consists mostly of insects, both on land and in the water. Damselflies most commonly feed on insects such as flies, mosquitoes, midges, beetles, mosquito larvae and water bugs. They grab their prey from the air or the top of the water. Some species of damselfly are known to eat larger insects such as moths, butterflies and also other species of damselfly and dragonfly.
Damselfly larvae are aquatic, living only in the water. They feed on other aquatic insects such as water bugs, worms, mosquitoes and flies. Damselfly larvae are also known to feed on tadpoles and small fish. They occasionally feed on the larvae of other damselflies and dragonflies as well.
