Japanese Beetle

Japanese beetles feed on about 300 species of plants, devouring leaves, flowers, and overripe or wounded fruit. They usually feed in groups, starting at the top of a plant and working downward. The beetles are most active on warm, sunny days and prefer plants that receive direct sunlight. A single beetle does not eat much, but it is the group feeding of many beetles that results in severe damage. They understand what can be accomplished by having many bodies focused on the same objective.

Japanese Beetle Life Cycle: From Grub to Adult

Japanese beetles hide out underground and overwinter in the grub stage. When soil temperature climbs above 50°F in the spring, the grubs begin to move up into the root zone. Following a feeding period of 4-6 weeks, the grubs pupate in an earthen cell and remain there until they emerge as adults.
