Adult beetles have a high demand for sugar. Whether flying, moving, mating or reproducing, they need a large amount of sugar to directly supply energy or synthesize proteins, lipids and other substances. A high-quality daily ration for beetles should be based on sufficient carbohydrates, supplemented by VB family and trace elements such as calcium, iron, zinc, selenium and potassium required by beetles.
YUE brown sugar jelly is a good choice, which is suitable for feeding most beetle adults.
