Yes, earwigs do eat plants. While they are often considered omnivores, their diet frequently includes various parts of plants.
What Do Earwigs Consume?
Earwigs are known to have a varied diet, making them both a pest and, at times, beneficial in a garden ecosystem.
- Plant Material: They consume leaves and fruits from a wide range of plants. This can include garden vegetables and herbs, sometimes to the detriment of the crop. For instance, they have been observed eating plants like basil, especially when their populations are high.
- Insects: In addition to plant matter, earwigs also feed on small, soft-bodied insects. This aspect of their diet can be helpful in controlling other garden pests.
When Do Earwigs Become a Problem for Plants?
While they are not exclusively herbivorous, earwigs can become a significant nuisance in gardens, particularly under certain conditions.
- High Populations: During rainy years, earwig populations can surge, leading to a greater impact on plants. When their numbers are exceptionally high, they may consume more plant material, including desired crops.
- Preferred Plants: They have a preference for certain plants, and their feeding can result in visible damage to leaves and fruits.
In summary, earwigs are opportunistic feeders that will readily consume plant material alongside small insects. Gardeners often notice their presence due to damage on various leaves and fruits.
