|Mating is usually in June and the females are passive. After mating, the females build one lenticular, multilayered cocoon in which they deposit their well-camouflaged eggs onto a bedding of silk. . After that, the females guard their cocoons, fasting and ignoring any disturbances. Just before the young crab spiders hatch, the females open the cocoons, thus helping the young with the hatching process. After this, the females die. |
|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 main food source of the Bibio marci are different plant juices, nectar and sometimes pollen. Bibio marci like living in bushes, shrubs or on small plants.|

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 encountered in greenhouses. After hatching from pupae, the females start feeding immediately. They drill small holes in the top surface of plants’ leaves using their ovipositors and suck up liquid with their mouth parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate int...|
...parts. The damaged areas on the leaf tissue (which also enable bacteria and fungi to penetrate into the plant) are clearly visible as yellowish stains.
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.
In vegetable plantations, chilli plants and potatoes are often affected. The females use their ovipositors to drill 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 ...
|...hora and Amegilla are active from March to June. They are often visible on deadnettle (Lamium) or on other species of the mint family (Lamiaceae), as well as on borage (Borago officinalis) and species of the primrose family (Primulaceae).
The females dig tunnels in loose soil for their nests. These tunnels are approximately 100 mm long and sometimes branched. It can happen that several females build their nests very close to each other. The nests are equipped with small chambersshaped like hazelnuts, which are smooth inside and treated with an antibiotic acting secretion. The front brood chamber is often filled with the food supply an...|
...ich are smooth inside and treated with an antibiotic acting secretion. The front brood chamber is often filled with the food supply and is meant to divert parasites’ attention from the brood in the rear chambers.
Before oviposition occurs, the females fill the brood chambers with a puree of pollen and nectar, on which they lay their eggs ,in a small puddle of nectar. The hatched larvae feed on the puree until early autumn, thereafter they pupate within the brood chamber. They overwinter as p...
|The body size of adult heather spiders varies. Females reach body lengths of 7 - 9. 8 mm, while males are 2 to 3. 6 mm in length. As is the case with most species of crab spiders, the heather spider has a bizarre body shape with bumps and pits. The colour of the body in the males and females is also different. In some specimens the whole body is one colour. The body colour of the females can range from white to pink or yellow, depending on the colour of the flowers they are visiting. This colour adaptation is possible within a few days, with the colouring is supported (surface dissolution) by dots and stripes. Male Thomisus onustus ...|
|On the front section of the body (prosoma), the foremost edge is elongated to both sides. In the males, the prosoma is yellowish-brown to dark brown. In pink females, the prosoma often has a wide, dark grey band at the edgesme. The prosoma is occasionally shiny and has a bright median stripe. The rear section of the body (opisthosoma) is shaped, more or less, like a triangle in both sexes. In the males, the opis...|
... The prosoma is occasionally shiny and has a bright median stripe. The rear section of the body (opisthosoma) is shaped, more or less, like a triangle in both sexes. In the males, the opisthosoma is yellowish green to brownish. The yellow (or white) females bear yellow or pink stripes on their opisthosoma, while the pink coloured females are often spotted with white.
|Due to their camouflage Orange tips mate in April or May. At this time the male orange tips (can be observed frequently at hedges and in meadows on their search for the shy and inconspicuous females. Oviposition of the fertilized females takes place separately (in rarer cases in small groups) do you mean that the eggs are usually laid singly on the preferred food plants of the caterpillars, such as the cuckoo flower (Cardamine pratensis), bittercress (Cardamine amara), garlic m...|
...me’s rocket (Hesperis matronalis), although this offers little food for the larvae. They prefer to visit plants in damp and half shady biotopes. Food plants are chosen particularly because of their ethereal oil (mustard oil) content, which the females detect using chemosensors, which are on their forelegs. In order to avoid egg laying on the same plant by other orange tips, the female leaves odoriferous substances (pheromones) on the leaves.

On the upper surface of the abdomen of the males are blue to blue-green or sometimes yellow pairs of spots; in the females greenish hues predominate. The females have an ovipositor at the end of their abdomens, whereas the males have claspers with which they hold the female during mating. The females have a cylindrical abdomen.|
|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 a...|
...olour, 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.
|The oblong, shiny metallic body of the Tetragnatha montana is a bit darker among the males and reddish in colour, while the drawing is nearly like that of the females. The females reach body lengths of 6-10 mm, the males, 6-8 mm. The front section of the females’ body (prosoma) is either beige-brown, tan or brown in colour. The sternum is dark brown to black, and sometimes has a dark edge. There are small bright spots beside the hips (coxes).|
