Ophiocordyceps sphecocephala is a species of parasitic fungus.

It is entomopathogenic, meaning it grows within insects, particularly wasps of the genera Polistes, Tachytes, and Vespa.

[2] Physically, its stromata can be 2–10 cm long, and form an egg-shaped head.

[2] The fungus has possible implications in medicine; it may have anti-asthmatic or anti-cancer properties.
