Yellow-shelled semi-slug (Parmarion martensi)

Janggel or yellow-shelled semi-slug (Parmarion martensi) is an animal species in Ariophantidae, semi-naked snails or has an internal shell which is very small, nocturnal but sometimes performs activities in the morning when the environment is wet, very moist and foggy.

P. martensi has a pair of antennas, a small and reduced shell wrapped in a mantle to form a bulge in the upper back to cover the head to half the body. The shell is brownish yellow, transparent, thin, shiny and shaped like a nail.

Dlium Yellow-shelled semi-slug (Parmarion martensi)

Yellow-shelled semi-slug has a length of 3-5 cm, yellowish brown or grayish brown or dark brown on the back. Two black parallel lines that extend from the base of the antenna on the head to the back of the body.

Janggel is found in andosol soils in mountainous and highland areas, tropical at an altitude of 750-3,000 m, pH 7, temperature 11-25C, humidity 80% and rainfall 2,500-7,000 mm/year.

P. martensi is often seen clustered with activities not far apart because of slow locomotion and move in a place not too far away. The eggs are often placed in groups with 10-15 eggs per group.

This species moves while secreting phlegm that is toxic to plants. They eat dead and living organic material including leaves, stems, flowers, fruit and other parts of plants that cause holes by bite marks on the surface. Sometimes it also takes root and shoots.

Mashpi walkingstick (Trychopeplus mashpiensis) from Chocó, Ecuador, based on males, females and eggs

NEWS - Researchers report Mashpi walkingstick ( Trychopeplus mashpiensis Conle, Valero & Hennemann, sp. nov.) from the Chocó ecoregion of northwestern Ecuador is new to science based on its unique body ornamentation and egg structure morphology. Trychopeplus Shelford 1909 is a genus of Neotropical stick insects (Phasmida Leach 1815) known for its remarkable morphological adaptations that allow it to blend in almost perfectly with epiphytic lichens in its habitat. These adaptations make Trychopeplus one of the most cryptic stick insect genera. The genus was described to distinguish the Neotropical species from Pericentrus Redtenbacher 1908 based on morphological differences and distinct geographic distribution compared to the type species Pericentrus moewisi Redtenbacher 1908. Pericentrus is known to be restricted to East and South Asia, whereas Trychopeplus is endemic to the Neotropics.

Giant shield bug (Pycanum alternatum)

Giant shield bug or pycanum rubens ( Pycanum alternatum ) is a species of animal in Tessaratomidae, has a large shield covering the back, shiny green-blue-brown colored and appears to have a powder or wax layer, inhabiting the leaves of plants in open forests or bushes . P. alternatum is also called a stink bug because of its ability to release pungent aromas when disturbed. These insects live solitary with a partner and usually the mother gather in a family together in nymphs. White eggs are attached under the leaves of the plant. Nymphs can be found in the same host as their parent. The nymph has a flat rectangular shape with a large vein in the middle like a flat leaf. Nymphs having striking colors are light green, orange and red. Color may represent various stages of development or gender. The initial stage has a small size and red color. It grows in a bigger size and turns orange then ends in green. Kingdom: Animalia Phylum: Arthropoda Class: Insecta Order: Hemipter...

Purwaceng (Pimpinella pruatjan)

Purwaceng or purwoceng or antanan gunung or Viagra of Java ( Pimpinella pruatjan or Pimpinella priatjan ) are small termas growing horizontally in Apiaceae, growing in villages on Dieng Plateau, Central Java Province, Indonesia, at 1,500 to 2,000 meters above sea level, the roots have medicinal properties for aphrodisiacs and are usually processed in powder form for a mixture of coffee or milk. P. pruatjan grows flat on the ground but does not propagate, small leaves are reddish green for 1-3 cm in diameter. This plant is only found in Java and grows in high mountain areas. A low population where industrial demand is very high results in increasingly scarce. Another place that is likely to become a purwaceng habitat is the Iyang Mountains and the Tengger Mountains in East Java Province. Efforts to multiply and cultivate have a big problem where these plants have difficulty producing seeds. In vitro propagation research through tissue cultivation has been carried out to overcome ...
