Sense: noun/1
'Insects' is the ordinary everyday word for small six-legged creatures such as ants, flies, and bees. 'Bugs' is looser and more casual, and many speakers use it for almost any small creature that creeps or flies, even when the science is not exact. 'Arthropods' is the scientific umbrella term that also includes spiders, crabs, and centipedes, so it is much wider than 'insects'. 'Spiders' are often called insects in casual speech, but they are a different group because they have eight legs and two main body sections. In daily conversation you might complain about insects in the kitchen, say bugs are all over the porch light, or use arthropod only in a science lesson.
