Diet

• Gryllodes sigillatus is an omnivorous cricket that feeds on a mixture of plant material, seeds, fruits, decaying organic matter and small animal material.

• It is an opportunistic feeder and can forage around human habitation where food scraps and other organic material are available.

• In Zihuatanejo, fallen plant material, garden debris and food residues around buildings can provide suitable food resources.

Range

• Gryllodes sigillatus, commonly called the tropical house cricket or banded cricket, is probably native to southwestern Asia but has been widely dispersed through commerce and is now established throughout many tropical and subtropical regions.

• It occurs in tropical and subtropical parts of the Americas, including Mexico.

• The species occurs in the Zihuatanejo region, where its warm climate and abundance of human-modified habitat provide favourable conditions.

• Around Zihuatanejo it is most likely to be encountered near buildings, paved areas, gardens and other disturbed sites rather than deep within undisturbed forest.

Habitat

• Gryllodes sigillatus is strongly associated with warm, human-modified environments and is frequently found outdoors around buildings and paved surfaces.

• It shelters in cracks and crevices, beneath paving, stones, boards and other debris, emerging at night to forage and call.

• In Zihuatanejo, suitable locations include patios, sidewalks, gardens, hotel grounds, residential areas and the edges of roads and other paved surfaces.

• It can occasionally enter buildings, particularly where sheltered crevices and suitable food are available.

Description

• Gryllodes sigillatus is a small, somewhat flattened cricket, generally about 13–18 mm long.

• Adults are light yellowish brown to tan, often with darker markings and a distinctive dark transverse band between the eyes.

• Males have short forewings that cover roughly half of the abdomen and are used to produce the calling song.

• Females are nearly wingless and have a conspicuous, slender ovipositor.

• The long antennae, pale coloration and flattened body distinguish it from the larger, more robust field crickets commonly encountered in tropical environments.

• Males call primarily after dark, producing a rapid series of brief chirps.
