There was once a bumble bee from the Lake.

At the beginning of the 90’s a Dutch entomologist, Von Asperen de Boer, discovered what he believed a new species of bumble bee, which was collected in the vicinity of Lake Villarrica (South of Chile).
In 1992 Von de Boer published a work where he introduced this new species Bombus villaricaensis¹.

What Von Asperen de Boer did not know is that 10 years earlier, the European bumble bee species Bombus ruderatus² had been introduced to Chile.
So, realizing that Bombus villaricaensis and Bombus ruderatus were the same species, the same author published a clarification note of his error in 1993, and thus B. villaricaensis became a synonym of B. ruderatus.

As part of my master’s thesis at the Department of Geography and Environmental Sustainability at Oklahoma University. I will be looking at the current distribution of this species in SouthAmerica. Most of the data will be provided by the citizen science project Salvemos Nuestro Abejorro.
