Chinese Grasshopper (Acrida cinerea)
by Dana Campbell
A. cinerea is a species in the silent slanted-face grasshopper subfamily (Acridinae). The 40+ species in genus Acrida lack stridulatory organs on their legs, hence they are “silent.” Acrida species are omnivorous; many are pests of agricultural crops including sorghum, wheat, rice, cotton, weed, sweet potato, sugar cane and Chinese cabbage.
A. cinerea, is found throughout China, Japan, South East Asia and Indonesia. It grows to 2-3 inches long, has a green or brown body, colorless hind wings and long legs that support long jumps and sustained flight. Historically it has been used as a human food source, recent studies have examined its nutritional value as a potential high quality and easy to rear oil source for the poultry industry…

![Tiny Katydid Ears Look Remarkably Human
by Stephanie Pappas
Their ears may be on their legs, but katydids hear a lot like humans do, a new study finds.
In fact, even though insect and mammal lineages diverged a staggeringly long time ago, even for the evolutionary scale, our ears have evolved to work in remarkably similar ways. The findings could be useful for engineering miniature sound sensors, said Daniel Robert, a bionanoscientist at the University of Bristol in the United Kingdom.
“It’s a bit of a breakthrough for us, because now we know that ears exist that can do such refined analysis [of sound] and yet be that small and that simple,” Robert told LiveScience.
Robert and his colleagues focused their study on the South American katydid Copiphora gorgonensis, an orange-face insect that can hear sound whose frequency ranges from 5,000 to 50,000 hertz. Humans, in comparison, can hear between about 20 and 20,000 hertz. These katydids sing at about 23,000 hertz, in ultrasound, or above the human range of hearing…
