> As I understand it, the honeybee was present in North America beginning about 100 million years ago and became extinct about 14 million years ago due to the advances of glaciers.
Hi all
100 million may be a bit of a stretch for bees in the USA, though the following is based on a fossil of one bee. Insect fossils are pretty rare
¶
Engel, M.S. & al. (2009) A Honey Bee from the Miocene of Nevada
The specimen described and discussed herein was recovered from the Late Barstovian (ca. 14–14.5 Ma) paper shales of the Stewart Valley Basin in west-central Nevada. Apis nearctica indicates that North America was one of the native regions of Apis distribution, where they became extinct sometime subsequent to the Miocene.

The Miocene Epoch, 23 to 5.3 million years ago, was a time of warmer global climates than those in the preceeding Oligocene or the following Pliocene
