After hatching, the maggots eat their way into and through the young sprouts and later feed on the young leaves of the grass plants. Further growth of such plants can be disrupted by this, or even prevented. The damage patterns on grass plants vary. Ragged, cracked leaves, are often seen, as are swollen stems at ground level or near the ground, or the formation of 3 to 4 stalks on the same plant. Seedlings may be cut off at the base. The maggots reach body lengths of up to 5 mm. Approximately 30 days after hatching f... | | |
| | Mating season is fromJuly /to September. The fertilized females lay their eggs just below the surface of the soil (usually in chaff or leaves). The larvae of Lagria hirta are cream to light brown in colour. They feed on rotting leaves or on peat. The development of the larvae from egg to beetle takes 9 months, from autumn to spring. Lagria hirta overwinter in the larval stage. In May of the following year, the larvae pupate and hatch as adult beetles. | | |
| The females lay their eggs on the underside of the leaves of the caterpillar’s forage plants, for example on willow, hazel, fluttery elm, field elm, mountain elm, hops, great nettle, gooseberry and raspberry plants. Around 250 eggs are laid separately. 2 - 3 weeks later the solitary caterpillars hatch. Dur...
...le on willow, hazel, fluttery elm, field elm, mountain elm, hops, great nettle, gooseberry and raspberry plants. Around 250 eggs are laid separately. 2 - 3 weeks later the solitary caterpillars hatch. During the day they stay on the underside of the leaves. The larval stage lasts 6 weeks and then the caterpillars pupate. The pupae are striking; the middle is constrictedly built and has a hump with shiny, metallic patches on the front and back. . The second generation of comma butterflies overwinter as... | | |
| | Mating season is in May. Most males die after mating - those that survive can be encountered until July. The females spin a flat cocoon covered with light coloured spider silk in the creases in leaves, rolled up leaves or under rocks for their eggs. Having finshed the cocoon, they spin themself a roof shaped shelter in which to reside, while guarding their brood. The spiders hatch and reach their final stages of development in autumn. The young spiders overwinter ... | | |
| ...and emerge as adult butterflies in May. The adult brown argus butterflies are active from May to June. During this time they mate and reproduce. The fertilized females always lay their eggs on the host plants of their larvae, on the underside of the leaves. The development from egg to caterpillar takes about 10 - 12 days. After hatching the caterpillars immediately begin feeding on the host plants and after about 60 days they have completed their development. They are greenish and have a pale line len...
...greenish and have a pale line lengthwise on each side. When they have reached a length of about 20 mm they pupate. They hatch from the pupae from late July to mid September and produce the second annual generation of caterpillars which overwinter in leaves in frost free places. | | |
| | The females lay their eggs in summer on the underside of leaves on foliage plants. The caterpillars initially live in tissue. The caterpillars are brownish in colour. From October on, they can be found on the ground, where they feed on the fallen leaves of willows and oaks. | | |
| | The mating season for southern green stink bugs extends from spring through to late autumn. The fertilized females lay their eggs on the leaves of different plants such as Crotalaria, wild blackberry (Rubus) and Cyperus rotundus. They glue about 260 barrel-shaped, whitish-yellow eggs to the surface of the leaves, in groups of 30 - 130. The eggs are about 1. 1 mm in length and 0. 9 mm in width and turn pink over time. | | |
| | This bug overwinters in the adult stage. It hides in fallen leaves, bark or in the hollow parts of plants. From May on the larvae hatch, which are green in colour and in July the adult stage is reached. The females lay their eggs on nettles on the upper side of the leaf stalks. Every year, a new generation emerge... | | |
| | Females are 20 to 28 mm in length. They overwinter in caves beneath the ground or in leaves. They lay their eggs in the spring, in mouse or mole holes, and even in walls or under rocks. The containments for pollen, honey and for the brood are built from wax. When the labor force hatches the nest expands to accommodate up to 500 bumblebees... | | |
