The beetle does not recognize its owner. Longhorn beetles are insects. Insects generally have low IQs and have no ability to identify their owners. However, after being kept for a long time, beetles will become familiar with the owner's smell and develop a certain conditioned reflex, so that they can actively accept the owner's feeding without attacking the owner.

Notes on raising beetles:

1. To raise beetles, you need to prepare a breeding box of appropriate size, either a wooden box or a tin can. If many beetles are raised together, the breeding density must be controlled to avoid cannibalism.

2. Longhorn beetles like to eat young leaves of poplar, willow, acacia and other trees. If these foods are not available, you can drip honey on mature branches. In addition, you also need to put some clean drinking water in the breeding box to replenish the beetles with the required moisture.

3. Longhorn beetles can fly, so the lid of the breeding box should be closed tightly. Some ventilation holes can be left around the breeding box to ensure that longhorn beetles can breathe normally.
