or Valanga nigricornis
The two belalang kunyit or valanga nigricornis are such a loving pair, choosing the stem of Okra to hold on to. The okra and winged bean which has been behaving like the legend of the three sisters (click: Unintended companionship of Okra, Roselle and Winged Beans. and Okra get entwined as in the Legend of Three Sisters Garden.), has leaves which change just a shade yellower to camouflage the pair. That must have been their master bedroom, five feet above the ground. They are fairly secretive with their endeavor, in fact it is me that is naughty, intruding into their privacy, without even knocking on garden's door.
In many insects and fish, the male is smaller than the female. In mammals, including humans, males are typically larger than females. In birds, males often exhibits a colourful outfit and display that attracts females.
Grasshoppers have an amazing ability to identify their mates. Each species has its individual song, produced by rubbing or flicking the lower back legs on the forewings to create either a chirping or a clicking sound . Females sing more softly than males, facilitating differentiation between both sex and species. Species that make no sound rely on sight and scent to find a mate. Males emit pheromones, external hormones which attract females, while other species use their excellent eyesight to enable identification by color.
Elaborate courtships routines are performed by males in some species. The American grasshopper Syrbula admirabilis displays 18 individual poses using its wings, legs, and palps. Males of other species may wave brilliantly colored wings when wooing the female, while other species forego courtship altogether.
Mating occurs when the male lights on the female's back and may last anywhere from 45 minutes to well over a day. In the species Extatosoma tiaratum, a female mates with several males. Most of the sperm in her genital tract from the first suitor is replaced by the sperm of her next mate. Males therefore mate many times with the same partner and other females to gain the maximum opportunity to pass on their genes. Males of some species die shortly after mating. The females die after egg-laying. (refer: Grasshoppers - Courtship And Mating).
A few days ago,
I heard continuous clicking sounds made by one belalang kunyit from the bush of ulam raja, now I know what the sounds for. a haunting serenade, a courtship after all...
