Beetles’ body shapes are very diverse as a result of adaption to environment. They can be long, lean, short and stocky as well as flat and sometimes streamlined. The structure of the beetle’s surface is an important criterion for classification. The surface can be smooth, ridged, shiny, grooved or with cavities and bumps. Beetles are sometimes bizarrely shaped as a means of camouflage.
Another important distinguishing feature is the color of the beetle, which varies as greatly as the body shape. W...

Another important distinguishing feature is the color of the beetle, which varies as greatly as the body shape. While most beetle species are dark or brownish in color, there are species whose surface has a luminous pattern or metallic sheen. | | |
| | Wall | | The wall (Lasiommata megera) is a species of butterfly in the family Nymphalidae. It is common in Europe, North Africa and Asia. The wall reaches wingspans of 40 - 55 mm. The upper surface of the wings is orange-yellow in colour with dark, jagged lines. There is a black "eye" with a white spot in its centre on the upper surface of the forewings. The underside of the forewings is similar to the upper surface. The hind wings have three to four eyes. The underside of the hindwing is grey and bears several small eyes. | | |
| These are very small flies, about 2-3 mm in length and their bodies are mostly yellow in colour. The head and antennae are bright yellow. The top section? the upper surface? of their chest (thorax) is shiny black. Their scutellum is also light yellow. They have markings on the upper surface. The females have an ovipositor on the end of their bodies.
The adult flies have a life span of about 1 week and only feed on vegetables (phytophagous). Aside from the open air, they are mainly encountered in greenhouses. After hatching from pu...
... have a life span of about 1 week and only feed on vegetables (phytophagous). Aside from the open air, they are mainly encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant) are clearly visible as yellowish stains.
The males liv... | | |

The hind legs have long hairs that aid in swimming. The water scavenger beetle prefers to live in and on smaller bodies of waters with sufficient sunlight. They 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 possibl...
...th 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, windows, etc.) having confused them with open waters.
After mating, the oviposition of the females happens in cocoons near the surface of water where the eggs are glued to water plants. Approximately 8-10 days later the larvae (with body lengths of 3-4 mm) hatch. They increase rapidly in size . The larvae feed (starting at the lastest three days after hatching) ) on smaller aquat... | | |

They feed, initally in groups and later alone, by scraping the surface off the leaves from the underside, leaving only the veins, unlike the adults. eats the leaves from the lower surface by scraping them off. The development of the larvae is complete in 3 weeks (June/July). They pupate in oval spaces in the earth just beneath the surface of the soil, where they remain for 8 to 11 days. In August the beetles of the new generation leave their pupae. | | |
| | The abdomen is long and flat and predominantly orange in colouron the upper surface and sides. The underside is black and only orange at the outer edges. The wing covers are black. They are finely haired which makes them appear lightly powdered. The legs are relatively long and also hairy. Their outer surface is black in colour and the inner surface is orange. Cantharis fusca can be confused with other soldier beetles (eg Cantharis annularis, Cantharis pellucida and Cantharis rustica). | | |
| | Adult female Chorthippus brunneus reach body lengths of 20 - 25 mm while the males are much smaller. The upper surface of their bodies is brownish. The patches of colour on the body differ in males and females. The abdomen has black and light stripes on the sides. The underside is much lighter than the upper surface. There are reddish spots on the upper surface of the last abdominal segments. The common field grasshopper can only be distinguished from similar species by the sounds it creates. | | |
| | ...Female maps of the first generation (spring) reach wingspans of up to 38 mm, those of the second generation (summer) reach 43 mm, while the males can reach spans of 32 mm in spring and 38 mm in summer. The body of the butterfly is slim and the upper surface is a black-brown colour. The underside is lighter and slightly hairy. The rings on the segments are white. The upper surface of the wings in the spring generation is a brownish-red to orange colour and is interspersed with black patches. The summer generation are black-brown to black or sometimes blue-black) The undersides of the wings in the two generations differ only s... | | |
| | The entire upper surface of the body is red with longitudinal black stripes. The sides of the abdomen are red with black spots. The pronotum (already said upper surface is red) has six black stripes. | | |
| This moth can reach wingspans of about 45 mm. The base colour of the forewings is reddish-brown. The upper surface of the forewings is divided into three sections by two transverse, light, wavy lines with dark edges. There is a row of dark brown spots from the centre to the outer edge of the forewing in the lower third which connects with the second line. The ja...

When the wings are outspread this dark edge continues on the hind wings’ upper surface - as also as the supreme line complained across the sub-wings is extended. | | |
