description Bombus pauloensis Overview
Bombus pauloensis is a species of bumblebee native to South America, with a range extending from Colombia and Venezuela through Brazil to Argentina and Chile. It is one of the few bumblebee species documented to exhibit facultative polygyny, whereby colonies may have more than one queen, and populations display notable geographic variation in color patterns across their range. The species is an important pollinator of both native Andean and subtropical flora and commercially managed crops, and it has been studied for potential use in greenhouse pollination.
