Do ladybugs have an exoskeleton

Yes, ladybugs (Coccinellidae family) have exoskeletons, or hard skeletons that are located on the outside of the body.

Specifically, ladybugs are insects. All insects have the following:

Compound eyes on their heads;

Head, thorax and abdomen as three (3) distinct body parts;

One (1) pair of antennae;

Skeleton that is hard and on the outside of the body;

Three (3) pairs of segmented legs.

Ladybugs have all of the above so they therefore have exoskeletons.
Yes, they do!
