There are bees that have not been seen since the 60’s that are not listed as endangered.

While the law lays out a process time of 2 years for a species to be listed, what we found is that, in practice, it takes, on average, 12.1 years," said Emily Puckett, who recently received her doctorate in the Division of Biological Sciences in the MU College of Arts and Science. "Some species moved through the process in 6 months but some species, including many flowering plants, took 38 years to be listed -- almost the entire history of the ESA."

After reading the document that listed Bombus Affinis as an endangered species I formed my own opinion by and it does not reflect well on the chemical industry.
