Copepods (/ˈkoʊpɪpɒd/; meaning “oar-feet”) are a group of small crustaceans found in the sea and nearly every freshwater habitat. Some species are planktonic (drifting in sea waters), some are benthic (living on the ocean floor), and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants.
Platerodrilus(Previously Duliticola) is a genus within Lycidae that are commonly referred to as Trilobite Beetles. The common name is derived from the appearance of the females (above), which remain in the larval form during adulthood, a process known as neoteny.
Trilobite beetles are usually found on the surface of rotting logs in lowland primary forest, where their diet is thought to consist of fungi, rotting plant matter and slime moulds. For such an interesting genus, very little is known about their life cycles and there has been minimal taxonomic work regarding the males of the species, which are illusive.

…a large species of stag beetle (Lucanidae) which inhabits tropical rainforests throughout Indonesia other areas in Southeast Asia. Dorcus titanus individuals can grow quite large with males averaging from 32-111 mm and females averaging 36-54 mm.
Questo magnifico chilopode (Scutigera coleoptrata) potrebbe essere il vostro migliore amico, sempre se una casa libera da cimici, zanzare, scarafaggi e pesciolini d’argento è il vostro ideale di casa, visto che mangia proprio queste cose.
Morde? Sì, ma solo se la prendete e la immobilizzate. Insomma, vi morderei anche io. E in caso di morso c’è un po’ di dolore e l’unico rischio è quello dell’allergia, perché nella stragrande maggioranza dei casi è totalmente innocuo (anche per i bambini e gli animali di casa).
Fate amicizia con la scutigera, non ve ne pentirete.
Known as the “tamamushi” in Japanese,
is a striking species of metallic woodboring beetle (Buprestidae) which is endemic to Japan.
typically occur in woods, forests, and other wooded areas. Like other Buprestids the larvae of C. fulidissima will bore through and feed on decaying wood.
Chrysochroa fulidissima is typically one of the species used in the art of “beetlewing” work due to its elegant green elytra.
The most notable characteristic of the phylum Arthropoda is the presence of jointed appendages. A second major characteristic is an exoskeleton. Unlike the cuticles seen in nematodes and tardigrades, the exoskeleton of an arthropod is made primarily of chitin and can be reinforced by the process of biomineralization (the addition of tough minerals and hardened proteins). The anatomy of arthropods divides the body into three main tagma. These tagma include the head, thorax, and the abdomen. In some cases two or more tagma can be fused. When the head and thorax are fused it forms a cephalothorax. When the thorax and the abdomen are fused it is called a trunk.
Subphylum Hexapoda (”six-footed”) contains insects. Their anatomy contains all three segments: head, thorax, and abdomen. Hexapods have one pair of mandables, one pair of antennae, and one pair of maxillae on their head. Additionally they have lips called the labrum and labium. This subphylum is characterized by its three pairs of leggs. Typically insects have two pairs of wings. Hexapods, like myriapods, use spiracles (holes along the side of the exoskeleton) and tracheal tubes (tubes that allow oxygen transportation around the body) for respiration.
