Abstract

Communication organs are poorly represented in the fossil record, so their evolution is usually reconstructed by comparison of extant species using a phylogenetic approach. We have analysed some extremely well preserved stridulatory and hearing organs of the oldest known bushcrickets from the lowermost Tertiary sediments of Denmark (55 million years old). These fossils indicate that males sang with a broadband frequency spectrum, and it is likely that both sexes could hear ultrasound. The fossil wings have lower asymmetry than extant species, indicating that bushcrickets may have evolved from a bilaterally symmetrical ancestor.
