| Pond olive dun | The pond olive dun (Cloeon dipterum), also called the small mayfly, of the order mayflies (Ephemeroptera), suborder split-back mayflies (Schistonota) and the superfamily Baetoidea belongs to the family of the Baetidae and to the genus Cloeon. This species is wid...
... family of the Baetidae and to the genus Cloeon. This species is widespread from Europe to Siberia to East Asia (Japan). It is mainly found in Central Europe, but is also encountered on an occasional basis in Northern and Southern Europe. The Pond olive dun reproduces twice a year,the first in May / June, the second in August / September. | | |
| | 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. The pterostigma is yellow or orang... | | |

Tabanus sudeticus reach body lengths of 19-25 mm. Their base colour is grey-brown. Their compound eyes are dark brown. The thorax of these flies is olive-brown to grey and has 3 weak longitudinal lines, which are somewhat brighter in colour. The dark brown segments at the rear end of the abdomen have a light-brown edge which gets wider at the sides. There is an even lighter coloured triangle in th... | | |
| | After 5 to 14 days the larvae hatch. At the end of the 3rd larval stage they are about 11 mm in length and pupate. The larvae of alder leaf beetles are first olive, later cyan and shortly before pupating bluish in colour. They have 2 rows of very hairy warts. The larvae, like the adult beetles, feed on the leaves of the grey or speckled alder (Alnus incana), hornbeam (Carpinus), birch (Betula) and hazel (Co... | | |

The head is large and clearly separated from the thorax. The compound eyes are blue-green in the males and olive-green in the females. The chest section is mottled yellow to green and has black markings (base colour). Two yellow stripes are visible on the upper surface and sides of the chest. | | |
| | ...f the pronotum. Both lines consist of 4 points. The scutellum is triangular in shape and slightly brighter. The wing covers (elytres) are approximately the same length as the pronotum. Their surface is densely dimpled and has a strong metallic, olive to bronze-coloured sheen. The hind wings are well developed and large. When the beetle rests, these wings must be folded in an intricate manner to fit under the wing covers. Spreading the wings is faster. This is done with the assistance of the le... | | |
| | Adult female Plagiognathus arbustorum reach lengths of 3.7 - 4.3 mm, while males range from 3.8 - 4.6 mm. Their bodies are elongated and the males are slenderer than the females. Plagiognathus arbustorum vary in colour from light olive brown to almost black. The head, front of chest and first two antennae segments are usually dark. The head is small, shorter than it is wide and strongly inclined backwards. The chest has a bright posterior. The chest and front wings are covered ... | | |
| | ...) in thick, wavy, golden brown hair, growing backwards. These hairs thin out over time and then 4 dark lines appear lengthwise. The males have thicker hair at the sides. At the edges of the scutellum are 6-8 long, black bristles. The abdomen is olive coloured with some light patches. The wings, span 12-16 mm, shimmer brownish, have black veins and overlap on the abdomen in resting position. The common cluster fly is cumbersome in flight. | | |

In male specimens the posterior part is often red or reddish brown in colour. The Pond olive dun is able to swim by moving its abdomen up and down (making a wriggling motion). 7 pairs of gills are located laterally, the first six pairs of which work almost continuously. At the end of its abdomen it has 2 long and hairy (whitish and fila... | | |
| | The Pond olive dun is considered a bioindicator and due to the contribution of its larvae to water clarification it is of great ecological importance. | | |
