|The young adult alder leaf beetle leaves its pupa in August and lives off the leaves of various trees and bushes until the end of September. These include alder (Alnus), willow (Salix), poplars (Populus), birch (Betula) and hazel (Corylus). At the end of September - beginning of October the alder leaf beetle hides in the ground, where it overwinters.|
|Half-spotted stink bugs prefer warm, sunny coastal areas with sandy soils, dunes and rich deposits of flowering plants, in particular the parsley family (Apiaceae). From April to September the half-spotted stink bug can be found mainly on beach thistle (Eryngium maritimum). It feeds on various plant parts. The half-spotted stink bug is ready to reproduce in September. |
|The green shield bug does not overwinter in the larva state. Mating and egg-laying take place in early summer. A female lays up to 100 eggs. The larvae hatch and go through 5 phases of development, becoming adults in September. During these phases of development the larvae remain together.|
|...ollen in it and then lays 5 to 15 eggs on the pollen. It also builds a second, slightly larger vessel for nectar (for food on rainy days) . In the period up to August the population of the colony grows from 60 to 150 animals. During the months of September and October the colony (with the exception of the queen) dies.|
|This hoverfly is found in Europe, Central Asia and North Africa from April to September. It mainly lives in gardens, where it can be found on Apiaceae or Umbelliferae (hogweeds, carrots etc). Its larvae develop in small, muddy bodies of water, but also in rotting holes filled with water in the branches of trees. |
|...size of a ball? football or tennis ball or what? The whole exterior surface of the nests is smooth. While the adult animals feed mainly on nectar, the larvae are fed on flies. The life cycle of Dolichovespula saxonica is approximately April to September.

|...ll. After egg-laying the cell is sealed. When the larvae hatch, they live on the pollen and nectar for weeks before pupating. The Anthidium manicatum reproduces once a year. The females are active from June to October, the males from June to September. On rainy days the animals take refuge in safe, waterproof cavities.
Dune robberflies live in sandy places. They prey on other insects and are very good hunters. They often sit on the bare, hot sand waiting for their prey which they catch and sting in the air.
The dune robberfly is active from June to September. The females have a ring of spikes at the end of their ovipositors which they use to make a hollow in the sand to lay their eggs in. The larvae usually move deeper into the sand after hatching.|
|... buildings, garages, sheds or blindboxes. When finished, nests consist of about 50 cells. They have no protective outer surface. Up to 30 workers live in a single nest. At the end of July, the adult females and males of the new generation appear. In September the wasps die with the exception of the fertilized young queens, which hibernate. |
|... the soil or on grass. The caterpillars shed their skin twice. They overwinter and pupate in May. The cocoon is spun on a blade of grass and is yellowish-green. The next adult meadow browns emerge in June.
The meadow brown is active from June to September. It reproduces once a year. |
