The Moth Urchin Fungus (Akanthomyces aculeatus) is a fungus that parasitizes and consumes adult moths. The mycelium creates a thick mat that encompasses the moth and sometimes adheres to adjacent surfaces. It can be found in the summer through fall in moist habitats. As the fungus grows, spear-shaped spikes protrude outward making it look like a sea urchin. The clubs produce spores in order to infect more insects. Spooky!
