March of the Mealworms
Lori Dunlap recorded these videos showing large numbers of Eurasian mealworms near her home. 29 and 30 August 2018, Sonora area. We see the larvae far from the house, near the house, taking refuge in joints in the concrete, in the garage, in the house, and in the tanbark.
And thanks to Warren Steiner… he had a better name for the video.
