Lady Bug Anatomy
Ladybugs are winged
insects (a type of beetle). When they are not flying, the flight wings are
covered and protected by a pair of modified wings (called elytra). When flying,
the elytras open up, allowing the wings to move.
The area above the elytra is
called the pronotum (it is part of the thorax). The pronotum frequently has grayish spots on it.
head of the ladybug is very tiny (and frequently confused with the pronotum).
Females are larger than males.
Like all insects, ladybugs have:
- 6 jointed legs (arranged as 3 pairs)
- one pair of antennae
- an exoskeleton made of chitin (a type of strong protein similar to the one
that forms our hair and fingernails)
- a three-part body consisting of the:
- head (which has the mouthparts, compound eye, and antennae)
- thorax (the middle section which is where the 3 pairs of legs and
the pairs of wings attach)
- abdomen (which holds the excretory and reproductive organs and
most of the digestive system)
