OE Life Cycle

Understanding the OE life cycle in butterflies requires a detailed examination of the pathogen's transmission, replication, and impact on its host.

Ophryocystis elektroscirrha (OE) is a protozoan parasite infecting butterflies, particularly monarchs. The OE spores adhere to the egg surface, and upon hatching, larvae ingest these spores.

Inside the larval gut, the spores penetrate the gut wall, entering the host's body cavity, where they reproduce asexually. As the butterfly undergoes metamorphosis, OE multiplies, forming new spores.

These spores are present on the adult butterfly's scales and abdomen, ready to infect the next generation. The OE infection can lead to reduced fitness, impaired flight, and decreased lifespan, greatly impacting butterfly populations.

Transmission of OE

Transmission of Ophryocystis elektroscirrha (OE) in butterflies primarily occurs through direct contact with contaminated surfaces, such as host plants, or through vertical transmission from infected adult females to their offspring.

The spores of OE adhere to the butterfly's body, especially the abdomen, and are transferred to milkweed leaves during oviposition. Upon hatching, larvae ingest these spores, leading to internal infection. Additionally, adult butterflies can spread spores through physical contact during mating or communal roosting.

The implications of OE transmission are profound and often emotional:
