| | After mating, the females construct a multilayered cocoon, in which they lay their eggs. They then watch over the brood, without eating. After the young spiders have hatched, the females die. | | |
| | In spring and autumn, the females dig tunnels into the ground, where they lay 50 - 90 eggs. The eggs, as well as the hatching larvae of the spring generation, are guarded by the females. The larvae shed their skin 4 - 5 times. They are similar to the adult earwigs, but are much brighter lighter in colour and without wings. They reach maturity in approximately one month. | | |
| | Philodromus dispar belong to the native medium-sized Philodromidae. Both the males and the females reach body lengths of 4-5 mm. Their bodies are flat and there are gender differences in colouration and markings. While the males’ base colour is very dark, sometimes almost black, the females are shades of yellow-brown The males have short shimmering hairs, which make them look shiny. | | |
| 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 bot...
...ar 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 ... | | |
| | After mating, fertilized Cerceris quadrifasciata females dig tunnels in the ground for oviposition. They then capture insects on which they lay their eggs. The hatched larvae feed immediately on the live and stunned insects which are brought in constantly by the females. | | |
| | Notably, the females’ clypei (the broad plate at the front of an insect's head) have smaller or larger bulges, which have a simple conical shape, or may even look like little horns. The mouthparts (mandibles) of the females are elongated and have a tooth-like appendage, to capture prey and facilitate their transport to the nest. Different species of the genus Cerceris can be recognised by the shape of their mouthparts. The abdominal segments are strongly constricted 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...
... 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 ang... | | |
| | Melanostoma scalare produce two new generations a year. The first new generation is active from April to May, and the second new generation, from September to October. The females of the first generation lay their eggs on the larval food plants in late May, and the females of the 2nd generation oviposite in early August. The larvae prey on aphids and other soft-skinned insects. After 2 months, they pupate and shortly afterwards emerge as adults. | | |
| | Melanostoma mellinum produce two new generations a year. The first is active from April or May, the second from September or October. The females of the first generation lay their eggs in late May, and the females of the second generation do the oviposition in early August on the food plants of the larvae. The larvae are initially blind. They prey on aphids, flies and other soft-skinned insects. After 2 months, they pupate and shortly thereafter emerge as adu... | | |
