Is a spider a bug

Technically, Spiders are not bugs since they are not insects. Not even all insects are bugs. Only insects belonging to the order Hemiptera are bugs.

Although, bugs may refer to any small creature with more than 4 legs. So it is possible; but Spiders are definetly not insects.

Okay, here are some quick facts. The term bug is defined as and insect or small arthropod. Arthropods include insects, arachnids, and crustaceans. Therefore, spiders are bugs. I have no idea why this is a debate when there is something called a dictionary to tell you what Words mean.
