Bumblebee Bombus atratus
On a very warm day at over 11,000 feet in the heart of Inca country in the Peruvian Andes, I was not expecting to see this impressive, black Bumblebee.
But there they were, in the heart of Cusco, working & buzzing away in the midday heat while we humans were seeking shade. Although in a hurry to catch a bus at the time, I had to take a few photos and record a short video.
"Bombus atratus" is a neotropical bumblebee that is found throughout regions of South America, including Colombia, Ecuador, Brazil, and Argentina. It lives in social colonies that include a founder queen/queens, workers and brood. "B. atratus" is somewhat unusual because of its potential to oscillate between polygynous and monogynous nesting cycles.
