Stick insects look like twigs is that an example bastian mimicry

Nope. Bastian mimicry is when a harmless organim disguises themself as a harmfull one. As for describing a stick bug I beleive the word you're looking for is camoflage.

Yes! Think about this:

A viceroy butterfly has the same markings as a bad-tasting monarch butterfly. *

It's basically like a white snake looking like a grey snake. Some people get confused with each of them, avoiding both of them due to bad information (ex. posionious, etc.) known for those creatures.

Hope this helps. :)
