| 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, f... | | |
|
| After mating, the fertilized females lay their eggs on the larval food plants. The larvae devour the leaves of various trees, shrubs and herbaceous plants. These include willow (Salix), poplar(Populus), alder (Alnus) and buttercup (Ranunculaceae). | | |

| ...d, chest (thorax) and compound eyes are black. The antennae are yellowish and comprise 7 or 9 segments. The abdomen is black and shiny and has a large reddish-yellow or yellow stripe in the middle of its upper surface. It is longer and wider in the females than in the males. The wings are milky-transparent. Their venation is clearly observable. The fore-wings lack the subcosta. Superposed in the idle state, the wings are ranging to the hind end of the abdomen. The upper section of the legs is reddish... | | |
|
| After mating, the fertilized females lay their yellowish to reddish-brown eggs, individually or in small groups, on the food plants of their larvae. The larvae are yellowish after hatching and resemble caterpillars. They have 8 small pairs of legs attached to the abdomen. Their antenna... | | |
|
| After mating, which takes place from early June on, the fertilized females lay single eggs into young caterpillars from the family owlet moths (Noctuidae), the species Euxoa tritici and turnip moths (Agrotis segetum) are the preferred hosts. After the larvae of Amblyteles armatorius have hatched, they eat the host caterpil... | | |
|
| After mating the females dig deep passageways, from 50 to 600 mm, into the ground, often with side galleries. The eggs are stored individually on pollen and nectar. When the larvae hatch they feed on the pollen and nectar until they pupate. The adult bees hatch in la... | | |
|
| After mating, the fertilized females lay their eggs on plants. The eggs overwinter. The larvae which hatch in late April, are also predatory. Excentricus planicornis are considered useful as they destroy many plant pests and are especially appreciated in orchards. | | |
|
| Mating takes place in late May to early June. The fertilized females lay their eggs in moist soil. The larvae hatch after several days. Their bodies have velvety black hair. They have strong mouthparts. The larvae of Cantharis fusca live on the ground or near the ground and capture small insects, worms and snails to ... | | |
|
| 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 we... | | |

| ...n (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.
