Common grass yellow (Eurema hecabe)

Common grass yellow (Eurema hecabe) is a species of animal in Pieridae, small butterflies fly close to the ground and open grass with scrub habitats, yellow and some black spots, usually show seasonal polyphenism and live in a colony.

E. hecabe with lepidopteran has a darker summer morph, triggered by long days of more than 13 hours duration, whereas diurnal periods shorter than 12 hours or less induce brighter morphs in the post monsoon period.

The upper wing on the front has two black stripes and a larger rectangular mark. Males and females have a sulfur yellow to lemon yellow wing surface depending on the season and location.

Eggs were laid in Abrus precatorius, Falcataria moluccana, Acacia, Aeschynomene, Euphorbiaceae and Cucurbitaceae etc. Females can distinguish colors when selecting host plants for oviposition. Larvae are long, green, leathery, cylindrical with large heads.

The pupa has long ribbons, rounded abdominal segments and wing flaps fused to form a deep sharp keel. The head shell ends with a short pointed snout. Solitary but sometimes on a large number of twigs. Some Wolbachia strains can change the sex ratio of species.

Most scientists and science activists have agreed that god is nonsense, delusional and cannot be accommodated in the theory of evolution. This opinion can be understood methodologically and I agree with the sentences. But so many behaviors are very real and occur in the field.

Javanese grasshopper (Valanga nigricornis)

Wooden grasshoppers or wooden walang or Javanese grasshopper (Valanga nigricornis) are grasshopper species in Acrididae and have around 18 subspecies, most of which are endemic to various island groups in Indonesia. This insect has a very broad sexual dimorphism where males have a length of 45-55 millimeters and females 15-75 mm.

V. nigricornis is yellowish brown or yellowish or green with bluish black marks. The back wing is rose red when flying. The nymphs are pale green and dark. They live in forests, bushes and really like the leaves of the giant sensitive plant (Mimosa diplotricha) and giant sensitive tree (Mimosa pigra).

Javanese grasshopper has one generation every year where four eggs are placed on moist soil in forest clearing. The eggs are not active throughout the dry season and it takes six to eight months to hatch.

The eggs hatch into nymphs and pass seven instar stages before becoming winged adults. Wood grasshoppers are solitary insects and do not form flocks, but outbre…
