Stick bugs have a selective diet, meaning they don’t consume just about anything. Not to mention, stick bugs are herbivores, foraging on some specific parts of plants. Let’s look into “What do stick bugs eat” by exploring their diet.

Insects, Animals, and Fish

Walking slowly from one leaf to another, stick bugs are therefore also called walking sticks. This behavior doesn’t make them capable of hunting or catching prey. Hence, stick bugs don’t eat insects, bugs, worms which can be harmful to them. And that’s also because they aren’t adapted to such an insectivorous diet.

Fruit, Vegetables, and Plants

Thriving on vegetation, stick bugs only stick to a plant-based diet, especially bramble, privet, and hawthorn. However, they are known to consume entire leaves, leaving nothing but a leafless tree.

Therefore, stick bugs eat plants, blackberry leaves, and leaves of other shrubs. Bramble and other fresh leaves make up their diet.

As a result, stick bugs benefit the ecological system by fertilizing it with their feces. However, they damage the vegetation in the case of infestation because of their consistent foraging.

When in captivity, stick bugs eat lettuce and blueberries. But they can only consume small bits of such fruit and veggies.

What stick bugs don’t eat?

Stick bugs are somewhat picky eaters, consuming fresh and growing leaves of the trees. Hence, stick bugs don’t eat hummingbirds, other bugs, spiders, and aphids.

Apart from this, stick bugs don’t eat their babies. And it is obviously because they are protective of their babies. As for other plants and vegetation, stick bugs don’t eat flowers.
