Distribution and habitat

edit

This species can be encountered exclusively in Sardinia, and is more frequently found in spring and summer in the southern part of the island, where it lives in dry natural grassland.[1]

Description

edit

The adult males grow up to 45.9–61 millimetres (1.81–2.40 in) long, while females reach 55–70 millimetres (2.2–2.8 in). The overall shape is typical of Pamphagidae and very similar to Pamphagus marmoratus, to the point that for a long time this species was reported as P. marmoratus before the works by Harz (1969[2] and 1975[3]) definitively separated it on the basis of the longer cerci, a different profile of the ultimate tergite and the shape of male genitalia. [4]

Biology

edit

Pamphagus sardeus, like the other Pamphagidae, is herbivore. Adults, especially females, rarely jump, look quite torpid and clumsy and can be easily captured with the hands. Although relatively widespread, it's not easy to meet and it never occurs in large numbers.

A lab audio recording attributed to P. sardeus is available on the Orthoptera Species File website.
