The Differences Between a Praying Mantis's & a Stick Insect's Metamorphosis
By Jessica Benes, June 02, 2011
The praying mantis reaches adulthood
when it has developed wings.
Praying mantises and stick
insects are both protective of themselves and good at hiding and disguising.
The two insects develop in a similar way but adapt to their surroundings
differently. Learn from the way the two handle their eggs and keep their young
safe from predators.
There are about 2,200 kinds of
praying mantises. They come from the class Insecta, and order Mantodea. Praying
mantises are relatives of cockroaches and termites. Mantises live in shrubs,
grass and trees where they can hide from predators.
There are about 2,500 species of
stick and leaf insects. Stick insects are from the class Insecta and order
Phasmatodea. They take camouflage to a new level by resembling sticks or twigs.
They can be in colors of brown, green, gray, black or blue. Stick insects hide
in plain sight by standing out in the open, very still.
Praying Mantises go through
hemimetabolism, or incomplete metamorphosis. This process is completed in three
steps: egg, nymph and adult. Females lay several egg cases (oothecae) a few
days after mating. The female will hang upside down from a branch, produce a
white foam and form the egg case from that foam. She'll lay her eggs and the
foam will harden to form a protective shield around the eggs. Each case
contains up to 200 eggs. These eggs will hatch four to six weeks later and the
tiny mantids will start to molt, or shed their first exoskeleton. The female
won't stick around to meet or raise her children. She won't even live much
longer. Siblings sometimes feast on one another as their first meal. The
growing mantids, or nymphs, look like their adult counterparts, but smaller.
The mantids get bigger with repeated growth and molting of the exoskeleton to
allow further development. Each stage is called an "instar." When the
mantid has developed wings, the instars have completed.
The stick insects also undergo
incomplete metamorphosis and have three stages of metamorphosis. There are a
few differences between the two insects. Female stick insects can mate to
produce eggs, or they can produce young without a mate. Eggs produced without a
male will always be female and young produced with a male have a 50 percent
chance of being male. Females use two methods of concealing their eggs.
Sometimes the female drops eggs on the ground in various random places to
prevent predators from feeding on a nest of eggs. The eggs look like fallen
seeds. Other times, the female hides the eggs in the ground, in plants, bark or
on the underside of leaves. The eggs of some species are covered by a hard
shell and a "capitulum" node on one end that contains fats and
nutrients. Ants are lured to eat the treat and discard the hard shell. The egg
then incubates where it was dropped in the garbage heap and the new nymph later
emerges. Some species have wings and some don't.
