| ...venger beetles reach body lengths of 4-9 mm. Their bodies are oval-shaped, with a very flat underside. They have a slightly metallic sheen, are deep black in colour and shimmer slightly bronze when seen in light.
Adults have short, club-shaped antennae. Their mouthparts (maxillary palpi) are elongated, yellowish to reddish-brown in colour and hair-like (filiform) and may be mistaken for antennae. The maxillary palpi like the antennae often have dark ends. On the wing covers (elytra) are 10 stripes of fine, puncture-like points. These stripes, which are lengthwise and become furrow shaped at the rear end, are the main distinguishing feature of the water scavenger beetle. Ad... | | |
| | Longhorn beetles are iridescent and can be encountered in a wide variety of colours- red, blue, brown, bronze, grey, metallic hues, green, black and white. Their most striking characteristic is their long, segmented antennae, which often point backwards and may exceed the length of the body. They resemble ibex horns hence this insects name. As the antennae are so long, they must be anchored stably to the head which leaves little space for the eyes. In many species therefore, the eyes grow around the base of the antennae from behind. The bodies of these insects are elongated and are often larger in the males. Although sometimes the opposite is true. | | |
| | | Its body is slender and dark brown in colour. Only the tip of the abdomen is somewhat lighter. The head and antennae are black. The antennae of the males are about twice as long as the body. The 1st segment is markedly thicker, wrinkled and densely pitted. The antennae of the females are about half the length of the males'. Thethorax is black. The great capricorn beetle can produce sounds by rubbing the prothorax and mesothorax together. | | |
| | The eyes of the larvae are red. Their antennae and legs are transparent, while the rest of the body is yellowish. From the beginning of the 2nd larval stage on (5 days) the nymphs start eating. The head, thorax, antennae and legs are now black. There is a yellow patch on each outer side of the upper surface of the chest. The abdomen is red, as are the 2nd, 3rd and 4th segments of the antennae. In the 3rd and 4th larval stages (7 days), the body shape changes and shades of green start to predominate in the colouration. In the 5th stage (8 days) the wings begin to grow. The abdomen is yellowish green now and has red spots on its axis in th... | | |
| | ...cerus insidiator reach body lengths of 10 - 15 mm. Their body shape is similar to that of Pentatomidae species, but they are not so broad. The upper surface of the body is reddish brown and the underside is yellowish-green. The head has strong, long antennae with 4 segments and greenish eyes. The head and antennae are also reddish brown. The pronotum is broad and bears remarkably sharp spikes. The scutellum is smaller than in Pentatomidae species. The wing covers are ridged and - and covered in black indentations. On the abdomen there is a significant edge in... | | |
| | ..., oval, elongated or compact and their colouring black, brown, yellowish-brown, red, reddish-yellow to yellowish green and dark green. The colours are combined in a variety of ways and the surface of the body can be dull or shiny. The conical shaped antennae of these insects are striking and can have 6 - 9 segments depending on species. On the lower jaw and lower lip are palpi which can be longer than the antennae. Water scavenger beetles hold air under their wing covers (elytra). | | |
| | ...fairy-ring longhorn beetle is the smallest species within the genus Pseudovadonia. Their elongated bodies are black and yellowish-brown to reddish-brown in color. The underside of their body is covered in gray hairs. They have black heads and black antennae Their eyes have a clearly visible edge on the inside. The antennae are situated near the eyes. The thorax is almost spherical and has a rough scattering of spots. An important feature is the Scutellum which backwards is shaped like a double peak. The wing covers of younger insects are lighter in colour (brownish-y... | | |
| | The mouth parts of phantom midges are atrophied and functional in some species and in others not. Phantom midges cannot sting. Their eyes do not touch but create a crescent shape around the base of their antennae. The long antennae of the males are feathered and comprise 13-15 segments. The pedipalps are divided into three to five segments. Dot eyes (ocelli) are not existing on them. The thorax (chest) has no continuous, V-shaped suture, as in the case of mosquitoes (Tipuli... | | |
| | The larvae of the phantom midges live (standing vertically) in water. Their body is transparent (glass rods larvae). They have antennae, which are also shaped in such a way as to function as holding devices for the capture of small insects (eg mosquito larvae) or crustaceans (eg Daphnia). The antennae are used to impale the prey, to crush it and to guide it into the larvae’s mouth. | | |
| | The antennae normally have 11 segments, all, or only the last four, of which are increasingly thicker towards the end, thus appearing club or bone shaped.In some species the antennae are threadlike or endpin-verse (with or without thickening). | | |
