All About: Flying Insects
Many types of flying insects are found in the
park. Dragonflies and Damselflies come in all different colors and are considered beautiful to many, but
did you know they’re very beneficial? They consume
numerous pest insects, including mosquitoes. After
being laid in the water, the
eggs hatch into naiads, or
Dragonfly nymph
aquatic nymphs, consuming
large quantities of mosquito larvae. They
live anywhere from 1 to 5 years in this
Dragonfly
stage before
molting into adults, living only a few
months.
Dragonflies hold their wings straightout while damselflies will fold their wings
back like a butterfly.
Damselfly
The Crane Fly is sometimes mistaken for a giant mosquito. These fragile flies
have extremely long legs, and in their larval stage live among decomposing leaves,
feeding primarily on organic matter. Adult
crane flies do not eat, nor can they sting or
bite. They are harmless.

Mayflies, also called dayflies, hold their 4 wings upright,
and have 2 to 3 long, hair-like tails. Female mayflies lay their
eggs in water, and newly hatched mayflies are called nymphs.
These nymphs live from a few months to 2 years, feeding on
aquatic plants and breathing through
gills. When ready to molt, the nymph
swims to the water’s surface, sheds its
skin, and takes flight. After shedding

its skin once more that same afternoon, the mayfly is considered mature and will mate. They orient themselves according to the moon, so bright lights will
attract a swarm. After mating the males dies immediately. Females live long enough to lay their eggs. Mayflies lack mouthparts and are unable to eat or bite.
The Lovebug is a member of the march flies. Eggs are laid
in grasses and weeds, hatching out, and living in a nymph stage
for most of a year. During this stage they will eat pieces of decaying plant matter, redistributing nutrients to the ground. After
molting in the spring or late summer, adult lovebugs mate and
will remain coupled for up to several days. During this time they
are beneficial pollinators, feeding on flower nectar. Females live
3 to 4 days, while the males live a
little longer. If you find squished lovebugs on your car it’s recommended to
wash them off with a non-abrasive
scrubber and soap that same day to
reduce paint damage.
