Common Green Grasshopper:

Common Green Grasshopper (2 sec. divisions)

This can be picked up on a detector, although, as our loudest grasshopper, it is very readily heard by ear. The sound is a persistent stridulation of around 15-20 seconds in duration.

Field Grasshopper:

The call of this species has almost no ultrasound. A faint sound was picked up on the detector at around 2 metres distance, when almost standing on the insect. The ears and the eyes are still superior for locating this grasshopper. The call is a brief ‘zip’ repeated about once a second.

Meadow Grasshopper:

The detector is useful for this species, as it doubles the normal range. The typical call is an intermittent series of ‘chuckles’ repeated every 1-2 seconds.

Mottled Grasshopper:

This can be easily heard by ear, but a detector does extend the range. The call is a series of around 15-20 short buzzes, rising in volume, before stopping.

Woodland Grasshopper:

It was not possible to get to a colony of this species in 2003, but Chris Haes advised that a detector was no help when he visited colonies on the Lizard peninsula.
