The Butterfly Stage:
After about a week the
chrysalis splits open and the butterfly emerges. The butterfly hangs
from the chrysalis for an hour or so to let its wings straighten out
from being crumpled inside the chrysalis. When hatched, fluid called
melatonin fills out the wings. A butterfly has a head, thorax, and
abdomen. It has four wings attached to the thorax. It has six legs
attached to the thorax, but only four are used. The first two legs
are kept folded up close to the head. The butterfly has two compound
eyes which have 10,000 lenses. The butterfly’s proboscis (tongue) is
split when hatched. It uses its two front legs to join the proboscis
together. The proboscis is a hollow tube like a drinking straw. Its
antennae is slender with a knob on the end and is used for hearing.
It tastes through its feet. The butterfly breathes through its sides
because it doesn’t have any lungs. A butterfly cannot bite or chew;
it only drinks nectar.
