The lower classifications of the longhorn beetle include the subfamilies, tribes, and genera within the family Cerambycidae. The family Cerambycidae is divided into several subfamilies, such as the Cerambycinae, Lamiinae, and Prioninae. Within each subfamily, there are numerous tribes, which are further divided into genera. These lower classifications help to categorize and organize the diverse species of longhorn beetles based on their evolutionary relationships and physical characteristics. **

The noises coming from the attic are likely not from house longhorn beetles. House longhorn beetles are not known to make audible noises that can be heard from the attic. Instead, the noises could be coming from rodents, birds, or other insects that have made their way into the attic.

To build a self-made hive with 3 layers for beekeeping, you will need to start by constructing the bottom board, which will serve as the base of the hive. Then, you can build the brood box, which is the main living space for the bees, and the honey supers, which are additional boxes for the bees to store honey. Make sure to include frames with foundation in each box for the bees to build their comb on. Additionally, you will need to provide an entrance for the bees to come and go, as well as a cover to protect the hive from the elements. It's important to research and follow specific measurements and guidelines for beekeeping to ensure the hive is suitable for the bees' needs. **
