|Ancylecha fenestrata adult female
The acoustics of this species are relatively poorly known, an audible defensive stridulation is made by both sexes. There are some reports (Scherberich et al, 2013) of the males having a calling song in the ultrasound, although I have not yet been able to confirm this (a signal matching their description that I recorded was later found to be interference on the power supply to the recorder, possibly from fluorescent light fittings).
I have several days and nights worth of recordings of the male, an isolated male and female, and a male and female in the same enclosure to process and hopefully identify a calling song.
Samples of the defensive stridulation will be added to BioAcoustica (Baker et al, 2015) (direct link to Ancylecha fenestrata page). There are already links to several publications on the sound production and hearing of this species.
