What conclusions can be drawn about an insect stuck in amber?

It probably crawled into the sap when it was still gooey, then got stuck. The sap dried and the bug was still there, and the the tree or whatever rotted away and then it was in the dirt for awhile and then there was an insect in the amber!

Maybe it crawled in there while it was still kind of sticky, and when it hardened up it became stuck.
