How some Brood X cicadas are infected with fungus

The video discusses cicadas that host a fungus, Masospora Cicadena, which alters their behavior and appearance. Cicadas spend up to 17 years underground before emerging, and some become infected by the fungus found in the soil. The fungus gradually consumes their bodies, leading to the release of spores that infect other cicadas. Infected males mimic female behavior to spread the fungus sexually. Despite severe physical changes, infected cicadas continue to behave normally.

How do infected male cicadas attempt to transmit the fungus?
