are crickets good for the garden

Crickets live all over Australia and you have probably heard them – but maybe not seen one.
Normally, Black Field Crickets are mostly a ground living insect, but will take to the air when numbers are too great and food becomes scarce.
Popular hang outs are corners, window sills, cabinets and couches. In the garden they eat insects, but once inside, the menu offers furniture fabrics, clothes, paper and kitchen scraps. Of particular attraction to crickets are wallpaper and its glue.
Black Field Crickets are widespread in eastern and southern Australia. It’s not hard to spot one jumping around as they grow to about 2.5 cm long. Their body and wings are brown, and their heads, long antennas and hind legs are all black. Adult crickets live for about three months.
Black Field Crickets have only one generation a year, with some overlap with the early and late stage nymphs and the adult crickets. It is usually only the adults which are heard and seen, as the youngsters blend in extremely well with tufts of grass.
These crickets love heavy clay-like soils which crack when they dry out. Cracks provide safe places for the crickets to hide during the day, especially when it is hot or there are predators such as birds around. At night, Black Field Crickets emerge to feed on plants.
Black Field Crickets are good buddies to have in your garden as they will help aerate your soil, which helps water penetrate into it.
Young crickets, known as nymphs, grow slowly through 9 to 10 nymph stages as they gradually develop into adults. Juvenile Black Field Crickets are similar in appearance to adults but lack wings and have a distinctive white band around their middle. It is only in the later nymph stages that they develop wings and females also develop an ovipositor.
Crickets have ‘ears’ in their legs just below their knees. The ear drums, one on each foreleg, are sensitive membranes which act as receivers of differences in pressure and can help crickets find a mate, be forewarned about predators or locate prey.
Crickets live all over Australia and you have probably heard them – but maybe not seen one. The most common is the Black Field Cricket. Only the male of this species ‘chirp’ by rubbing their wings together. They do it to attract females, to woo them, and to warn off other male competitors.
