| ... in the Mediterranean region, all the males are bright red. The eyes and legs are red and there is a red, or orange-yellow, basal spot on each hindwing. The abdomen of the males is very long and there are pincers at the end that are used to hold the females during mating. | | |
|
| Females are light brown, olive brown, olive green or ochre in colour. The basal spots on their hindwings are yellow or yellow-orange. The wingspan of the scarlet dragonfly is 55 - 70 mm. Between the wing approaches a light narrow dorsal line can be detected... | | |

| Fertilized females lay their eggs from the air, dropping 20 - 30 of them, each about 0. 5 mm in length, into vegetated waters. The larvae need to stay at the bottom of the water for about 1 year in order to develop. They live off captured micro-organisms until they ar... | | |
|
| Adult Orthetrum cancellatum reach body lengths of about 50 mm. While both sexes are pale grey-green when they hatch, marked differences in colouration occur later on (sexual dimorphism). The females become a yellowish colour. With increasing age, this changes to brown and then darkens and they are finally olive to green in colour. The males are pale blue to grey blue. | | |
|
| The forewings are colourless and have a span of 75 - 100 mm. There is a black marking (Pterostigma) on the wing tips of both sexes. The anterior area and base of the wings are yellow in colour, often to the knot. In older females (by separated wax particles) there can be a weak blue pattern. The hind wings are 35 - 41 mm long and 2. 3 - 3. 5 mm wide. When sitting, the black-lined skimmer raises its 1st pair of legs on. | | |

| ...blishes a territory and the males occasionally patrol this near the surface of the water. Competing species of dragonflies are systematically expelled from the area. The black-lined skimmer is very shy and always maintains a greater flight distance. Females usually remain hidden in the riparian vegetation and only rarely appear. They hunt in the evening and can only be observed flying in daylight during the mating season. Mating starts in the air and is completed after 5 - 10 minutes on a solid surface... | | |
|
| Mating takes place in late spring or early summer in sunny weather. The fertilized females lay their eggs from the air while clinging to the male (tandem flight). The eggs are attached to plant parts located under the surface of the water. | | |

| ...k 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. | | |

| ...day they hide behind loose bark, in old tunnels or in the leaves of their home tree. The strong locatedness of the Great capricorn beetle (the beetle flies only short distances) significantly restricts its dissemination. After mating, the fertilized females lay 60 - 450 eggs in portions of 1 - 3 eggs in fissures in the bark of old oak trees. | | |
|
| Acorn weevil live everywhere in the distribution area of the oak and are found from May to August come in deciduous forests, parks, or sometimes in gardens. After mating, the fertilized females look for an unripe acorn hanging on a tree, which they pierce with their long proboscis. When they have penetrated deep enough into the core, they lay 1, 2 or sometimes more eggs. As the acorn grows and matures the hole closes from the outside. Appr... | | |
