- Habitat loss: The clearing of forests and other natural habitats has reduced the amount of suitable habitat for Christmas beetles to live in.
- Pesticide use: The widespread use of pesticides has killed many Christmas beetles and other insects.
- Climate change: The changing climate may also be having an impact on Christmas beetle populations. For example, warmer temperatures may be causing the beetles to emerge earlier in the year, when there is less food available for them.
- Disease: Christmas beetles are also susceptible to a number of diseases, which can kill them in large numbers.
