All three larval stages feed on decaying organic matter, humus and plant roots in the soil but it’s the last stage which causes the most damage due to their feeding in autumn and winter. Quite the same Wikipedia. The chafer beetle life cycle is typical of other beetles in the Scarabaeidae family of beetles. Pasture management should be based on principles of achieving maximum growth of high-quality pasture at all times of the year. At present, no chemical pesticides are approved for use against cockchafers, and only biological measures are utilised for control: for instance, pathogenic fungi or nematodes that kill the grubs are applied to the soil. They have deeper rooting, are more tolerant of waterlogging and quicker to recover after summer. The larvae, known as "white grubs" or "chafer grubs", hatch after four to six weeks. collect. Jim Dixon, in Kingsley Amis's comic novel Lucky Jim (1954), repeatedly calls his department head, Professor Welch, an "old cockchafer". These new plants may survive as weakened and sparser pastures prone to weed infestation or may often die. The cockchafer should not be confused with the similar European chafer (Rhizotrogus majalis), which has a completely different life cycle, nor with the June beetles (Phyllophaga spp. Redheaded pasture cockchafers seem to favour egg laying in longer pastures in spring for increased survival of its eggs and young larvae. In the past, damage occurred every other year, because of the two-year life cycle of the cockchafer. The preferred food for adults is oak leaves, but they will also feed on conifer needles. Low soil temperatures in winter slows down the larval activity but this resumes when the soil warms in late August with feeding continuing till early summer. ), which are native to North America, nor with the summer chafer (or "European June bug", Amphimallon solstitiale), which emerges in June and has a two-year life cycle. When many larvae are present, pasture root systems are cut about 25mm below the soil surface.

This requires pastures to have 2.5 to 3 leaves before grazing and a grazing residual height of about 5cm between clumps after grazing. Unlike the blackheaded cockchafer, Acrossidius tasmaniae, which comes to the surface to feed on green pastures and clovers, the redheaded cockchafer grubs remain below the surface at all times. Once abundant throughout Europe and a major pest in the periodical years of "mass flight", it had been nearly eradicated in the middle of the 20th century through extensive use of pesticides and has even been locally exterminated in many regions. As such, the name "cockchafer" can be understood to mean "large plant-gnawing beetle" and is applicable to its history as a pest animal. They emerge from the ground and fly during January to February dusk on calm, mild evenings. The wetter seasons results in a substantial reduction in their population possibly due to drowning, disease and being trampled by animals. The common cockchafer lays its eggs in fields, whereas the Forest Cockchafer stays in the vicinity of the trees. Since World War II, it is associated in Germany also with the closing months of that war, when Soviet troops advanced into eastern Germany. Oats, but not wheat, may also be drilled into infested patches to replace missing green feed, as oat roots are seemingly not attacked by redheaded pasture cockchafer larvae. Cockchafer larvae can spend up to 4 years in the ground developing. The life cycle of the common cockchafer (Melolontha melolontha) has the following stages: egg, three larval instars, a pupal instar and the adult beetle.

Unfortunately, this leaves a soft seedbed which may lead to pugging, resulting in less dense pastures if the paddock is too wet when grazed. The cockchafer grub, which is the larval stage of the life cycle, are typical white curl grubs which tend to form a C-shape upon exposure or when handled. Perhaps in years of expected cockchafer damage (after long dry periods the previous year) consider leaving pastures in the north-facing paddocks short in late spring by either grazing them well or cutting them for silage.
