Black Soldier Flies, unlike houseflies, are known to be shy and avoid human. Normally they prefer sticking close to their own companies. However, they tend to also have a liking to stick to our colleague, being able to sit on her throughout the day even as she moves about.
This video shows how Fifi has become a Black Soldier Fly-Friend. She was casually walking when a female BSF landed on her palm and laid her eggs. It seems like Fifi is a parent now!
