| Bibio marci have relatively short antennae (9 sections ). Females and males can be easily differentiated by their eyes. . The males have hemispherical shaped eyes, while the female's eyes are small and on the side of the head. The females are smaller than the males. The males typically let their legs hang down in flight and are rough and hairy. The females are predominantly smooth. The wings of the females appear black, the wings of the males, white.

The autumn spider can be encountered in a wide range of environments, at various altitudes. It prefers semi-open habitats such as forest edges, clearings, box, trees, lawns, gardens, hedgerows, bogs and swamps, where it can be found as a ma...
...aiting for prey. In case of danger or disturbance, the spider falls back into the vegetation and adopts a special posture as camouflage. At to the soil the autumn spider can often be found in the company of spiders from the family Linyphiidae.
Males survive mating, which occurs in September and lasts only a few minutes Before mating takes place a number of sexually mature males appear in the vicinity of the orb-web of the female , where they wait for the female’s readiness to mate. If an insect gets caught in the female’s web, the males race towards it and the fastest spider wraps the prey in silk and offers it as a "bridal gift" to the female. While the female spider eats the gift , the successful male starts a courtship ritual during which it drums and plucks at... | | |
| | | Adult Anthaxia Podolica reach body lengths of 4. 5 - 6. 5 mm. The wing covers of the males are green to dark green in colour, while the females’ are a dull, dark copper colour and have a green spot where they join. The males bear two black, oblong patches on their pronotums. In the males, the 8th to 10th antenna segments are as wide (or almost as wide) as they are long. The average width of the females’ antenna segments is slightly smaller. From the 5th segment on, the males’ antennae are reddish. The wing covers (elytra) are slightly elongated, narrow rounded and at the tips are slightly trimmed. The exterior (outer edges) blends into a sharp angle. Their surface is granulated, covered in dots and has a weak sheen. | | |
| | Adults can reach body lengths of up to 8 mm; the females are usually 5-7 mm in length, the males, 5 mm. The body of the rabbit hutch spider, especially the males, is flat. The body colour varies from shades of red to brown. A distinctive characteristic is the oily sheen, which originates from their bodies and earns them their name with regards to the latin name. While females are generally reddish brown in colour, the males are rather darker brown. The underside of the body is pale brown. The entire body and limbs are covered in fine light hair, the thickness of which can only really be seen under a microscope. | | |
| | The abdomen (opisthosoma) of the rabbit hutch spider is flatter than the prosoma and that of the males has a sharp edge at the front. While the upper surface of the rear part of the females’ body is usually purplish -brown, dark brown or, in rarer cases, yellowish-brown in colour, the males are darker and have a clear oily sheen. On the side of the upper surface is a small bright yellow to off-white stripe, which sometimes has an indistinct marking on it. This can be completely absent on the body of the males. The females have two white spots which develop with age into two broad stripes. Near the outer sex organ (epigyne) - the females have a white spot, flanked by bright stripes. | | |
| | Adult scarlet dragonflies reach body lengths of 40 - 45 mm. Their colouration varies. In Central Europe brownish-red males are often encountered, while for example 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. | | |
| | The thorax in both sexes is yellowish brown to olive-brown. The abdomen of the females isup to 34 mm in length and dark with a mesh-like pattern and 2 black bands running lengthwise. In older females the abdomen may turn blue (through coverage with wax). The 2nd to 7th abdominal segments of the older males (excreted by wax that adheres to the surface) are also a powdery blue. The abdomen of the males reaches lengths of 30 - 35 mm. Young males also have a lattice like pattern on the abdomen. The tip of the abdomen - 8th to 10th segment - darkens considerably after mating. | | |
