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.

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.
