Pheidole tertiaria

紹介

Pheidole tertiaria is an extinct ant species known only from fossil specimens dating to the Late Eocene epoch, roughly 34 million years ago . The species was originally described by Carpenter in 1930 from compression fossils found in the Florissant Formation of Colorado, USA . Only two queen specimens have ever been documented, and the worker caste is completely absent from the fossil record . Because this species is extinct, you cannot keep it in captivity. There are no living colonies or individuals available. If you want to keep a living Pheidole species, the hobby offers many options like Pheidole noda, Pheidole megacephala, and Pheidole pallidula. These living species show the typical Pheidole traits you can actually observe and care for.
