|Adult specimens can reach body lengths of 5 to 9 mm. Including their long (and hairy) tail appendages total lengths of 8 to 17 mm are possible. Their long and slender bodies are yellowish-brown in colour sometimes with a green shimmer. The head is light coloured with a central marking in yellow, gray, brown and reddish-brown tones. Their two large compound eyes are brown in colour. Their mouth parts are atrophied because they mostly do not eat and live of fluid. The surface of the thorax is yellowish, reddish and whitish in colour and has a wide, somewhat darkened median stripe, in which a bright line runs length...|
... yellowish, reddish and whitish in colour and has a wide, somewhat darkened median stripe, in which a bright line runs lengthwise. The scutellum (small triangular plate on the thorax) is bright turquoise. Each segment of the abdomen has a light brown andreddish brown pattern on it and a long shiny green stripe lengthwise on the upper surface. 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 a...
|Male Omocestus rufipes reach body lengths of 12-17 mm, females 18-24 mm. The males are always darker than the females. The females usually have black brown, greyish brown to yellowish-brown or very occasionally reddish brown sides with shiny green backs, while the males have dark brown to black sides with yellowish brown backs.
The underside of the body of both sexes is (moving from front to rear) first green, then yellow then red. This colour change constitutes the most important identifying characteristic of the species.

|Euthrix potatoria is a medium-sized moth, reaching wingspans of 40 - 65 mm. Its body isyellow, brown or reddish brown in colour. The head and neck are thick with long hairs. The base colour of the wings is ochre -yellow to reddish brown. The wings of the males can have a purple sheen and are usually darker than the females’.
There is a dark brown diagonal stripe in the anterior third of the upper surface of the forewings, which extends up to the wing edge, and which remains visible when the wings are folded. Another transverse line in the same colour can be found in the posterior third of th...|
...an be found in the posterior third of the wings’ upper surface. It runs from the wing joint to the wing tip. About halfway between these transverse lines, is a less distinct, wavy line. In the centre of the wings’ upper surface, between the two dark brown, transverse lines, are two different-sized, predominantly white patches, which have a thin, dark circumference and a brown core (usually). The drinker can be confused with other eggar moth species such as the plum lappet (Odonestis pruni).
|Adult females can reach body lengths of 3-5 mm, males, 3-4. 5mm. The sexes are similar in shape and are light brown, reddish-brown or dark brown in colour. The front part of the body (cephalothorax) is pale yellowish brown to reddish brown in colour and without markings. The weak dark side edges are often difficult to recognize. On the surface of the back are dark-brown stripes which widen in the direction of the eyes without touching them. The front eyes and rear side eyes are close together. Sometimes they even touch. The deep black fangs (chelicera) are compared with the enlarged eyes. Their poison claws are lon...|
|Tabanus sudeticus are the largest species of horse fly in Central Europe. They are widespread throughout the entire Palearctic eco-zone.
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 the middle of each of the 2nd to 5th segments.|
|The upper section of the body (prosoma) has dark edges and is a glassy, yellow to light brown colour. On the upper side is a black marking which resembles a "Y". The sternum is dark brown.
The rear section of the body (opisthosoma) is oblong. The basic colours of the upper side are white , yellow , green or reddish-brown. . At the upper section of the opisthosoma is the characteristic leaf-shaped marking (folium) , which varies in colour (often in highly-contrasting red tones). The underside is yellow to brown in colour, with one dark and two bright stripes in the middle.
The legs of the autumn spider are yellow to light brown in colour and have indistinct dark spots and rings. The midfoot (metatarsal) of the first leg pair is (on the ventral side) slightly hairy, ( on the ventral side).
Due to its appearance, the autumn spider can easily can confused with the small a...|
|The reddish-yellow to reddish-brown pronotum has a faint white line in the centre, which is also sometimes absent. The colour of the scutellum is similar to that of the pronotum but is brighter at the end. The end is split in two. The abdomen is oval, has markings in black and oc...|
...two. The abdomen is oval, has markings in black and ochre and is partially covered by the wings. The penultimate (6th) segment of the abdomen has a black upper surface with five, bright irregular spots. The edges of the abdomen have a yellowish-brown and black pattern. The wingspan is about 14 mm. The front section of the wing is leathery and has a fine, dense stippling, while the rear section has a glass-like shine with numerous veins. The legs are brown to yellowish-brown in colour with brown spots.
|The most striking feature of this fly is the large, bloated-looking head. At the front is a translucent, dark brown bubble. The face of the Sicus ferrugineus is yellow. The lower part of the face is shiny, while the crown and forehead are dull coloured. The large compound eyes are chestnut-brown. The antennae are short and reddish brown and the 2nd segment is often as long as the 3rd. The proboscis consists of two sections and is dark brown to black-brown in colour. The cheeks in the side view appear substantially narrower than the compound eyes. A shiny, black patch is visible on the chest (thorax) - between the hips of the front and middle legs couples The abdomen, which is usually folded forward w...|
|The anterior section of the body (prosoma) of the females is brown and has thin, white to pale yellow or cream-coloured edges, which appear clearly separated. In some specimens light radial stripes can be seen. The prosoma of the males is dark brown to black, has short hairs and a clear white stripe on both sides. The upper surface of the rear section of the body (opisthosoma) of the females is light brown to brown with dark edges. In the middle, an indistinct leaf shaped pattern (folium) is usually visible. Towards the back of the abdomen is a marking in the shape of an arrow or angle. Brown spots can sometimes be seen on the front of the abdomen. The sides are white to cream-coloured or light yellow, with the edges clearly separated. |
