Kinda like a web crawler? (Sorry, obligatory Tech Talk reference.)

Spiders aren't insects, but they are bugs (of the arachnid persuasion).

All <strike>crustaceans</strike> arthropods are bugs, then?

My wife and I are trying to define "bug". She holds that it's related to the ratio of guts to appendages, or "squishability to crunchiness". Therefore a slug is not a bug, but a millipede is. A caterpillar, though, is right on the cusp.

She doesn't explain just what's on the the other side of the cusp from bug. Worm?

Bugs are actually an order within the family of insecta.
Spiders are not even insects, let alone bugs! ;)

True bugs= Hemiptera (http://www.insects.org/entophiles/hemiptera/)



There are about 4500 species of true bugs.

Most true bugs have 2 pairs of wings, though some can be wingless. The fore wings are partly horny at the front and covered with soft membrane in the back. When the bug is at rest the fore wings are held flat over the back and cover the hind wings. The membranous tips of the fore wings overlap in this position.

True Bugs have mouth parts made for piercing and sucking, sometimes, plants, other insects or blood. Their mouths are set up with 2 pairs of needle like tubes, one pair does the piercing the other takes care of the sucking.
