The Eastern White Grub is originally from the eastern United States and measures approximately 3-7 centimeters in size. Its color is slightly brighter than the Western Yellow Grub, with more and larger spots on its elytra. Among the species of the genus Dynastestityus, it has the shortest thoracic horn, which makes it even more adorable.

Eastern White Grub: Also known as the Eastern White Grub, it is a crawling animal belonging to the order Coleoptera, family Scarabaeidae, and genus Phyllophaga. It is originally from the eastern United States and can be found in almost one-third of the eastern region of the United States. However, despite its wide distribution, the annual collection of Eastern White Grubs is lower than that of Western Yellow Grubs. This is because the Western grubs have smaller habitats and more concentrated populations, making them relatively easier to collect.
Entomophilic friends recommend raising the grub. It is a small grub with a male body length of 4-6cm. The larvae can emerge in about a year under artificial rearing conditions. The adult body is green or yellow, and some individuals are gray. The elytra are covered with black spots. It is similar in color to the Hercules beetle and belongs to the same genus, but it is much smaller in size and is very suitable as a pet insect.
Keep the humidity and temperature stable to prevent dehydration and death. During the dormant period, provide a dark environment and a container that doesn't need to be too big. Use wood chips or sphagnum moss as bedding and maintain proper humidity. The depth should be sufficient to bury the adult beetle completely in the soil or sphagnum moss, which will make them feel safer. Place objects such as tree bark on the surface to allow the adult beetles to turn over. Occasionally, the dormant grubs may climb to the surface. Without tree bark to help them turn over, they will waste energy and may die. Maintain a temperature between 22 to 28 degrees Celsius. The higher the temperature, the shorter the dormant period.
The method of breeding larvae: Usually, it is best to have a relative space of more than 4-5 liters per larva. Individual feeding: Each larva is fed separately in a container, although it requires a large space, it can increase the chances of breeding large individuals. The disadvantage is that independent feeding may cause male and female larvae to mate at different times.
Improvement method: 1. When changing the soil each time, the remaining old soil in each box can be mixed with the new soil and distributed to each feeding box. 2. During the mid-stage of the third instar, mixed breeding can be carried out, but the individual weight of male and female may decrease due to mixed feeding, but not much.
Mixed breeding: Although it occupies less space, the size of the bred males and females will vary greatly, but the time of eclosion will not be much different, and the larval period is shorter than solitary feeding.
Larval period: About 14 to 26 months. Larval food materials: 99 Insect Humus + 99 Insect Fermented Wood Shavings in a ratio of 1:1. The humidity can be slightly higher than that for breeding, and a few pieces of wood can be added. Generally, most longjaes are artificially bred, so it is necessary to pay attention to whether the adult has passed the dormant period before mating.
If the adult has passed the dormant period, almost all of them will start to feed. You can use the touch method to see if the adults have threatening actions and strong claws. If so, it means that the adults have passed the dormant period and can be mated. Feeding supplies: Feeding box (large organizing box), 99 Insect Humus, 99 Insect Humus Leaf Soil, adult climbing bark or wood pieces, etc.
