What do gypsy moths feed on?

Gypsy moths primarily feed on the leaves of hardwood trees, which is the reason why the selection of this answer is appropriate. As larval caterpillars, gypsy moths have a particular diet that includes various temperate hardwood species. They are especially known to favor species such as oak, aspen, and birch, which provide their nutritional needs during their instar stages.

Their feeding habits can lead to significant defoliation of trees, which can weaken or even kill the trees if infestations are severe. This feeding behavior is a critical aspect of their ecological impact and is important for understanding their role as pests in forest management and landscape care.

The other options, such as pine needles, grass blades, and flower petals, are not typical food sources for gypsy moths, as their life cycle and development are closely tied to the foliage of hardwoods. Understanding the diet of pests like gypsy moths is essential for developing integrated pest management strategies in landscaping and forestry.
