Reading.
Butterflies are insects.
Just like all other insects, they have three body parts
(the head, thorax, abdomen), six jointed legs, two knobbed antennaes
and compound eyes. They also have four
large wings that are normally covered by colored scales. They also have a proboscis to suck or sip
nectar from flowers. The proboscis is
like a long tongue. Their bodies are
covered by very tiny hairs. Moths have
more hair on their bodies as compared to the butterflies. The hairs help them to feel the environment
and get information when they are flying.
Butterflies and moths are classified under a group of
insects called, Lepidoptera. This is
from the Latin words “lepido” for scale and “ptera” for wings but take note
that there are some moths that do not have wings. Notice the veins in the wings? These veins supply nourishment or blood to
the wings. The wings will become ragged and the colors fade as they age.
Butterflies cannot fly if their body temperature is less than 86 degrees. They need to warm themselves up in the sun in
the cool weather. Butterflies come out
only during the day but are most active in the mornings. They go out to warm themselves in the sun.
