Giant
Winged Insects
The largest winged insect in the world
is the Queen Alexandra Birdwing butterfly,
with females being the
larger of the species having a wingspan of up to 12 inches (30cm). Female
Ornithoptera alexandra (the scientific name for these giant
butterflies) are not as brightly colored as the exotic males, which
have irididescent scales of green, lavender, and blue. Not only are
these magnificent creatures extraordinarily beautiful, they are also
very rare. Queen Alexandra birdwings are found living only in remote
jungles of Papua New Guinea.
Queen Alexandra birdwing butterflies
are truly an exotic species; they live in the tropical jungles, they
occur in only one location in the world, and they are highly specialized
with very specific adaptations to their native ecosystem. Alexandras
are rarely seen by people, even in their native habitat, because they
spend
much of their short lifespan in adult
form (about 3 to 4 months) floating above the jungle canopy. Like all
butterflies, Alexandras do not have mouths with teeth, but rather a
straw-like "tongue' used for sipping nectar out of flowers. They
play an important part in their ecosystem, helping to pollinate flowering
plants that are out of the reach of other insects and animals. Also,
like many exotic species living in the tropics, Alexandras are poisonous.
They don't have stingers or fangs, but their bodies contain highly toxic
fluids that deter other animals from eating them. The bright colors
on the wings serve as a warning to potential predators - "I taste
really bad, and I'll probably make you sick". Unfortunately, none
of these adaptations have made them resistant to humans. Deforestation
in Papua New Guinea is causing loss of habitat for these rare butterflies,
and their spectacular size and exotic beauty make them especially attractive
to people who collect butterflies and insects. Queen Alexandras can
no longer legally be collected from the wild because they are a protected
species.
This
gigantic moth is called a Hercules or Atlas Moth
and it has been known to grow up to 11 inches (27cm). Like the Queen
Alexandra butterfly, the Hercules moth is an exotic species living in
the tropical climates of Southeast Asia. The males and females of this
moth species have the same coloring and markings, which are quite elaborate.
The outer tips of the forewings have the shape of a snake's head from
the side, complete with an artificial "eye". This is probably
to scare off birds that might consider eating the moth, but would have
second thoughts if it looked enough like a snake.
Is it a Moth or Is It a Butterfly?
Some moths are so brilliantly colored
and fancy that it would be easy to confuse them with a butterfly. The
way you tell the difference between moths and butterflies is; moths
have very specialized antennae, which look feathery. Butterfly antennae
are thin, narrow, and generally end in a "club", or swollen
tip. When moths land, they hold their wings open and folded over the
back while resting, and they tend to be active at night. Butterflies
are usually active during the day, and when they land to rest, they
hold their wings erect and closed.
