System for
orthoptera, such as crickets, with an
enclosure 1 defining a cavity 4, a
habitat structure 8 with a plurality of vertically extending channels 10, a collection region and container 14 for frass directly beneath the channels, and access means, such as a closable opening 16, to remove the frass or
orthoptera from the structure. The frass or
orthoptera may be removed while the
habitat structure remains in situ. There may be a flexible climbing means 18, such as string or
rope, to allow crickets to
climb up into the channels. There may be a region above the
habitat for holding food. There may be a lid or heater. 21 The habitat structure may be carboard sheets 9 or egg cartons. A method of raising and harvesting crickets is also disclosed, which comprises locating eggs or nymphs in the
enclosure, killing or incapacitating the orthoptera when they are ready to be harvested, and removing the orthoptera which have fallen into the collecting region from the
enclosure. The orthoptera may be killed by heating.
