I was shown this Friesella schrottkyi 🐝 colony living in a waste container on the University of São Paulo campus. Some stingless bees choose unusual places to nest!

This Trigona hyalinata 🐝 colony is now at least 23 years old. After a scare and some major rebuilding by its' workers in 2023 it seems to be in good health. There are reports of 60 year-old stingless bee colonies, some claim colonies can reach more than a century #Dynasty

Tandem running in 🐜 is a fascinating communication behaviour & is often considered a case of animal teaching.
But what do follower ants actually learn?👇

After a long search & seeing many stingless bees on flowers, it was an exciting moment to finally find a nest, probably Hypotrigona sp., in a Mopane tree (northern South Africa). Jumping spiders are a common sight at entrances🕷️ 🐝
