When she is ready she seeks a male, copulates and heads rapidly for the ground Pyllophaga is again a genus, consisting of more than 260 species of scarab beetles from the New World. In the spring, from April to late June, the adult beetles emerge from the ground and gather near the tops of deciduous trees to mate. This can lead to Small species, such as the garden chafer and the European chafer, pass through the developmental stages from egg to third larval stage in just a few months. Over a period of two weeks, they lay approximately 60 to 75 eggs. Each of the three segments behind the head bears a pair of well-developed thoracic legs. Pronotal pubescence fine and dense, especially towards the lateral margins. Chafer grubs found in compost heaps and organic rich soil are often Rose Chafer larvae which do not normally damage plants and are part of the composting process. When people talk of Chafers 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. subterranean cell that they make in early June and the developed adults emerge These microscopic animals can be watered into the lawn or garden border when the ground is moist and soil temperature range between 12-20ºC (55-68ºF).

With white grubs, the June beetles are brown headed at this stage. feeding on plant and tree foliage the females mate and lay their eggs into the top by small, parallel rods. Small species, such as the garden chafer and the European chafer, pass through the developmental stages from egg to third larval stage in just a few months. towards the end are flattened and plate-like which gives the appearance of a Hatching from the eggs, the beetles enter into their larval stage. We aim to enrich everyone’s life through plants, and make the UK a greener and more beautiful place.
