Summer's Love Bugs

Just the
mention of the word “bug” makes most people start scratching. However, there are insects that people,
especially kids, love. For grown-ups,
they bring back nostalgic memories of summers during their childhood. Who doesn’t remember the glass jar at the
foot of the bed with those sparkling, enchanting lightning bugs flickering off
and on?
Aztecs thought they brought a spark
of knowledge in a time of ignorance and darkness. Europeans believed that a person would die if
a firefly flew in the window. Native
Americans caught them and smeared them on their faces and chests as
decoration.
Today, the firefly is the state
insect of Pennsylvania and Tennessee.
They are used for medical research in the areas of cancer, multiple
sclerosis, cystic fibrosis and heart disease.
Fireflies are truly beneficial and don’t bite, have no pincers, don’t
attack, don’t carry disease, and are not poisonous. Their larvae feed on the larvae of snails and
slugs.
If you are really ambitious, you can
become part of a lightning bug network and help with research. The Museum of Science in Boston allows you to
sign up and send them data about the lightning bugs you observe once a week in
your back yard.
So the big question is why do
lightning bugs flash anyway? As you
might guess, they are trying to attract a mate.
The females perch close to the ground while the males fly around
flashing, and then a dialogue soon begins.
Each species of lightning bug has a unique flash pattern.
Bioluminescence is the ability of a living
organism to give off light which is referred to as “cold light” because no heat
is present. The firefly is the most
common land animal that has bioluminescence, but certain types of worms, fungi and mushrooms also display light.
Fireflies are most often found
around low, wooded areas that retain moisture like ponds and marshes. Adults sometimes feed on pollen and
nectar. The female lays her eggs in the
ground, and they hatch in about 4 weeks.
If you want to try to attract the golden
creatures, there are several things you can do.
Try to reduce the amount of light on your property so there will be no
interference with the signals they are giving each other. Instead, install lights that are low to the
ground and point straight down. Don’t use
bug zappers or chemical pesticides. You
could enhance the moisture available by adding more birdbaths. Allow for some tall grass in the yard where
the males can rest during the day.
Take your children and yourself back
to a slower, more beautiful time and have a lightning bug night often. The summer is short and so are
childhoods. If you want to learn even
more about fireflies, go to www.squidoo.com and research with your
children.
