| The upper surface of the wing covers (elytra) is covered, almost evenly, in spots and has short hairs which stick out slightly. The markings on the wings are unmistakable. The elytra are bright red with a black patch in the shape of a heart or sometimes a triangle, in the middle. This patch tapers off into a dark, narrow stripe that runs along the inner edge of the elytra to the tips which are also black. | | |
| ...b-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. Additional rows from irregular posited series of poi...
... are often found (as adults or larvae) floating on the surface of salt water or brackish water (mixture of river and sea water). The adults eat rotten plant debris. They surface for air head first and trap air to breath under their wing covers (elytra) and "row" themselves along by alternating the hind legs, wiggling from side to side as they swim. Their eyesight is not very developed. Therefore, it is possible for the beetles to land on? reflective surfaces (wet or shiny car roofs, ... | | |
| | | Adults can reach body lengths of 6.5 to 8.5 mm. They are oval in shape and domed. Most parts of the body are a shiny dark metallic blue colour , with green or brass-like tones. Their forewings (elytra ) are reddish-brown and (when closed) show an approximately equilateral triangle at the upperside. The elytra are coarse to finely covered in small holes. Depending on light conditions, the head and scutellum appear black, dark blue or bronze-green in colour.

The edges of the pronotum also have a distinct antennae furrow. Close to the middle of the black elytra ( wing covers) a broad white stripe can be seen, and there are white spots laterally at the end. The elytra have reddish scales at the seam where they meet and above the peaks. | | |
| | Hispella testacea | | Hispella testacea belong to the family leaf beetles (Chrysomelidae). They are about 4 - 5 mm in length and brown to dark brown in colour. The elytra and pronotum are covered with spines. They look like little hedgehogs. | | |

| | Adults can reach body lengths of 3-5 mm. Their elongated, domed, dark bodies have a strong metallic sheen, which is bronze, copper, blue, dark green and (more rarely) black in colour. The metallic blue-green to blue or black forewings (elytra ) have clearly visible dots, which run in multiple rows lengthwise. The head, scutellum and legs are a similar colour to the body but diffusely spotted have a scattering of dots. At the rear end of the body is a defensive gland, whose secretions ... | | |
| | The antennae are black, long and threadlike. The wing covers (elytra ) are hairless and are densely covered in fine dots. The alder leaf beetle lives in the most diverse biotopes, is day active, and is found particularly frequently in flat country. It prefers damp areas, in which alder (Alnus) bushes or trees ... | | |
| | The wing covers (elytra) also have a lace like surface. This structure, in addition to the structure of the antennae and the body shape, is an essential feature in the identification of the various species and gave rise to their common name in both English and German. Here... | | |
| | ...idae vary according to species and may be flat (subfamily Silphinae), elongated (subfamily Nicrophorinae) or oval. The basic body colour of most Silphidae is black or dark brown. Some species have reddish stripes or patches on their wing covers (elytra.) Some Silphidae are yellow and have black spots. | | |
