File:Paltothyreus tarsatus, Ophiocordyceps species (João P. M. Araújo).jpg

Palthotyreus tarsatus biting onto a green stem. Once infected by an Ophiocordyceps species (still undescribed), it climbs up to a vertical stem to die biting onto it. In this case, the fungus we see is actually a hyerparasite of the Ophiocordyceps fungus, which overcame it and procuced these torrubielloid sexual structures. (© João P. M. Araújo)
