Brief SummaryRead full entry
BiologyEggs are laid in underground chambers from early spring to the end of July. These are tended by the female until they hatch two to four weeks later. Nymphs begin to mature from the following spring onwards; but some may not mature until their third spring. Adults and nymphs can be found throughout the year in extensive tunnel systems that may reach a depth of over one metre. Mole crickets are omnivorous, feeding on a range of soil invertebrates and plant roots; often leaving neat circular holes through the roots of tuberous plants. Males occasionally produce a soft, but far-carrying 'churring' song from within a specially constructed chamber in the burrow system, which acts as an amplifier for the song, which is likely to be used for attracting females. The song is typically produced on warm balmy evenings in early spring between dusk and dawn, and it is similar to the song of the nightjar Caprimulgus europeaeus.
