Alcatraz is even more exciting that I had previously thought! Early last year the National Park Service had baited rats on the island with a non-toxic fluorescent food dye so they could track the animals as they left behind fluorescent droppings. Volunteers from the UC Davis entomology club along with workers then searched the island using black lights to find evidence of the rodents. Finding fluorescent millipedes instead was quite a surprise for the UC Davis entomology group! Dr. Robert Kimsey and his student Alexander Nguyen are studying what makes the millipedes glow. I can’t but wonder if the bugs just happened to eat baited rat food. Whether they became fluorescent by natural means, or by ingesting fluorescent dye, they certainly are a beautiful sight.
