Hello, I'm an expert in entomology, the scientific study of insects. When it comes to the impact of insects on the environment and human life, it's important to consider a variety of factors.

Darkling beetles, which belong to the family Tenebrionidae, are generally not considered "bad" from an ecological perspective. They play a crucial role in breaking down organic matter and recycling nutrients in the ecosystem. However, like many insects, they can sometimes become a nuisance if they infest stored food products, particularly grains and seeds.

It's also worth noting that some species of darkling beetles are known to be agricultural pests, while others are harmless or even beneficial. The impact of these beetles can vary greatly depending on the species and the context in which they are found.

In summary, whether darkling beetles are considered "bad" depends on the specific circumstances. As with many creatures, they are a part of the natural balance and can have both positive and negative impacts depending on their interaction with humans and the environment.
