| The yellow swarming fly reaches body lengths of up to 2 mm. Its body is yellow with black markings. Its head is very broad and there is a round black spot on a yellow background between its compound eyes. The spot is located in a wedge-shaped strip of dark hair, which tapers towards the front. On the yellow thorax are 3 wide, black stripes lengthwise. The stripe in the middle reaches from the neck to the scutellum. The outer stripes are shorter. Beside each outer stripe is one more black stripe which is much thinner and only half as long. The yellow swarming fly’s wings are transparent and extend far beyond the end of its abdomen in resting position. The wings are well developed, unlike those of other frit fly species. The halteres are white. The scutellum is yellow and has no markings. On the upper surface of the abdomen, which is yellow, are 4 black crossways. The legs are a weak brownish-yellow colour.

...as black spots and ligatures. It is covered in fine hairs.
The head is spherical and black and the antennae are very small and thin. The third segment of the antenna is very short and with apically thin hair. The proboscis is strikingly large, yellow in colour and appears slightly darker at the end. In the resting position it lies on the belly amongst the legs. The proboscis is stretched out before eating takes place. The chest (thorax) is very rounded, yellow on the sides has a big, black shiny patch on the upper side. This patch is joined to broad longitudinal stripe which extends to the head. At the thorax’s sides there are large scales under which the halteres are covered. The abdomen is yellow and with black spots on the top as also with three black bandages , which to the rear end are wedge-shaped and extended. The legs are long , thin and from reddish-yellow to yellow in colour.
The Taurus fly feeds on the nectar of the various plant species whose blossoms she visits. The female lays her eggs on branches of trees or on blades of grass. The number of eggs (located singly or in or in small clusters) can amount ... | | |
| | | The black chest section (thorax) bulges at the shoulders. These bulges are yellow. The triangular scutellum is also yellow. The first abdominal segment also has yellow bulges at the sides. The entire abdomen is yellow and black and is thus wasp-like in appearance. In the females only the 2nd and 3rd segment have a yellow stripe at the rear edges. The 5th and 6th segment look like they are covered with dull yellow dust. | | |
| | Adult Sphaerophoria scripta reach body lengths of 8 - 11 mm and are thus the longest hoverflies. Their abdomens are long and very thin. They have a distinctive marking which can vary They are black and yellow in colour. The males abdomen is club shaped and the females’ is ovoid. The face and the forehead are bright yellow. Their eyes are hairless. They have reddish-yellow antennae. The thorax has brownish yellow stripes on its sides. The wings are transparent and significantly shorter than the body. The legs are yellow. | | |
| | The adult common yellow dung flies reach body lengths of 5-12 mm. They are brown, yellowish-brown, golden, yellow (male) to yellowish-green (female) and are covered in dense furry hair. Common yellow dung flies have yellow faces with whitish-gray or sometimes slightly brownish foreheads. In the centre of their chest section (mesonotum) is a narrow red stripe. Their antennae and proboscis are black and their legs are yellow.

| | Adult Helophilus pendulus reach body lengths of 10 - 14 mm. Their faces are yellow and have a wide black stripe in the middle. The antennae are black with yellow bristles. The thorax is black with 4 longitudinal yellow stripes. The scutellum is brown. Helophilus pendulus have pale wings with a dark patch at the edge. The wings have a slight brownish tint. The abdomen has a black base colour and a striking marking on its surface in yellow, white, red and brown. The legs of Helophilus pendulus are yellow, with black and red sequences. The hind legs are broader. | | |
| 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 ...
... she takes position on a mating string at the rear of the web. After mating the male spider leaves.
The female autumn spider creates several white, round cocoons onthe branches or the bark of trees for the protection of the eggs. Up to 100 yellow eggs are laid in these cocoons. A few days later the female autumn spider dies. The eggs overwinter in the cocoon. The new generation hatches in spring.
Some natural enemies of the autumn spider are: insectivores, birds and other spiders from ... | | |
| | The European paper wasp has variable yellow and black patterns on the abdomen. The head is yellow and has a black spot in the middle. The antennae are yellow from the 3rd segment on. The underside of the last abdominal segment is yellow. The European paper wasp lives in open, warm habitats and is often found in human settlements. The adults feed on nectar and the larvae prey on insects. | | |
| | The adult butterflies (imagos) reach wingspans of 40 - 50 mm. The colour of their bodies varies widely. On the upper surface, brownish and reddish hues dominate. The head, chest and abdomen have brownish-yellow hair. Their forewings have a brownish-red upper surface, with a striking pattern of yellow to orange-red spots. There is always a black "eye" patch with a white core near the wing tips. On the bright seam of the wings runs a thin margin. Near the “eyes” are more patches of yellow. which run parallel to the outer edge of the wings. The outer edges of the forewings are convex. The underside of the forewings is a brownish colour and is mottled black, yellow and white. There is one white "eye" patch near the wing tips. | | |
| 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 encountere...

The males live on nectar or honeydew but they can live without nutrition until they mate. The females lay their eggs on the food plants of the larvae, for example chrysanthemums (hence their name) and gerberas.

...l into the upper side of leaves and place 50 to 100 (sometimes even up to 400) eggs there. The hatched larvae develop rapidly. At the end of the third and last larval stage the bodies of the larvae can reach lengths of up to 3 mm. The bodies are yellowish-white in colour and have no legs. The larvae remain in the leaf and bite twisting (serpentine like) passageways into the cell tissues by moving their mouth hooks up and down. Hence the English name "Serpentine leafminers" for the gen...

After 4 days the larvae are fully developed and leave the leaves’ interior, through a slit, in order to pupate. The development from egg to pupae (reddish-yellow to brown in colour) to adult takes about 17 days.
Endoparasites are natural enemies of the Chrysanthemum leaf miner larvae, for example, the larvae of the ichneumon wasps Dacnusa sibirica and Diglyphus isaea. The ichneumon wasps lay their eggs i... | | |
