Life cycle
The insect hibernates in the soil, in the form of a pupa... If root crops suddenly remain in the field, the larvae preserved in them can also successfully overwinter.
When the air temperature is reached + 15-17 ° С flies start flying. This pest loves the shade, it is found in damp, shaded areas, near water and hedges made from live shrubs. In open areas, the fly is less harmful.
Flying insects lay eggs in May: from the 15th to the end of the month... If the spring is cold, laying can occur in early June, when a couple of leaves appear on the carrots. Females lay their eggs in the ground near the plants.
Individual insects live for about 12 days. Their summer and egg-laying period is 1-1.5 months..
Larvae appear for 4-17 days after the eggs have been laid. It depends on the temperature. They feed on plant juices for about 3 weeks, after which they crawl into the soil, where they begin to pupate.
Having pupated, insects crawl to the surface. They form the second generation of garden pests. Their years starts in mid-July and ends in mid-August..
Females lay their eggs in densely growing crops. In autumn, some of the larvae manage to pupate, while others end up in storage with the harvest, where they continue to damage it, feeding on the juice of vegetables.
Important: The danger of an insect is that roots damaged by its larvae cannot be stored for a long time. As a result, most of the crop dies.
What does the pest eat?

- the leaves of the plant turn purple, after which they turn yellow and dry;
- winding passages, transverse cracks are visible on root crops;
- carrots become ugly, they have pronounced constrictions.
If the plant is severely damaged, it may die. Typically, root lesions are located close to the point of root growth. In vegetable stores, the larvae crawl from one carrot to another, penetrating into the core. Externally, the damage looks like those caused by wireworms.
Important: If plants with reddish-purple leaves are found in the garden, they should be pulled out immediately. This will help keep the rest of the roots from larvae.
