Nemobiinae Explained

Nemobiinae is a subfamily of the newly constituted Trigonidiidae, one of the cricket families. The type genus is Nemobius, which includes the wood cricket,^[1] but members of this subfamily may also be known as ground crickets or "pygmy field crickets".

Characteristics

Nemobiinae are typically small insects, generally less than 15mm long, and less robust than many other crickets (e.g. those in the Gryllidae). The thorax is densely bristled and the abdomen is also bristly. There are four (or sometimes three) pairs of long, movable spines above the tip of the abdomen. The ovipositor varies from being long, straight and needle-like, to short, curved and sabre-like.^[2] These crickets have wings of variable lengths and are generally brown, a suitable colour for concealment among the leaf litter and plant bases where they live. They are often active during the day and can be quite common in woodland and pastureland. They are omnivores. There are about two hundred species worldwide.^[3]
