How to Identify Rose chafer?

Life Cycle of Rose chafer
Egg The eggs of rose chafer are laid in the soil or decaying material. They are small and oval, usually white or pale in color. As embryonic development progresses, the shape and color remain largely the same until larvae emerge.
Larva Larvae of rose chafer are typically grub-like, with a soft, elongated body. They lack wings and have a voracious appetite for organic material. During this stage, they grow significantly, molting several times as they increase in size.
Pupal The pupa of rose chafer is quiescent, encased within a cocoon or pupal cell. It is here that drastic transformation occurs, reshaping the body from larval to adult form. The size is set but the shape and features within the cocoon change profoundly.
Adult Emerging from the pupa, the adult rose chafer's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction and sometimes feeding.

How Can You Attract Rose chafer
For attracting adult rose chafer, sweet substances such as ripe fruits or sugary solutions can be used as they are known to feed on nectar, plant sap, and fruit.
Rectangle
Habitat Preferences of Rose chafer Through Different Life Stages
The rose chafer larvae generally reside in decomposing wood or compost piles, where organic matter provides their nutritional needs. For the pupal stage, one might search close to the larvae's feeding grounds, usually within rotting logs or underneath the detritus where they form cocoons. Adults of rose chafer, meanwhile, are often found in flower-rich habitats like gardens, meadows, and hedgerows, feeding on pollen, nectar, and sometimes fruit. To observe the adults, one would ideally visit flowering plants on sunny, warm days when these beetles are most active.
Rectangle
When is the Best Time to Observe Rose chafer
The best time to find rose chafer is during the warm months of spring and summer when they are most active.
Rectangle
What is the Best Weather to Observe Rose chafer
Sunny and warm weather conditions are preferable for finding rose chafer as they are less active in cold or rainy weather.

How and Where Can You Find Rose chafer at Different Life Stages
Larva Rose chafer larvae can usually be found in decaying wood or compost heaps. To find them, gently sift through the decomposing material.
Pupal Rose chafer pupae are often located within the soil or leaf litter. Carefully dig in soil or search through leaf litter near the habitat of the larval stage to find them.
Adult Adult rose chafer can be spotted on flowers, particularly roses, or feeding on overripe fruits. Look for them in gardens or areas with flowering plants during sunny days.
