Both fungi and insects possess chitin-based exteriors. Also, both are heterotrophic, i.e., acquire nutrients by feeding on other organisms. It is at this nutritional interface where fungi and insects often intersect, giving rise to many different types of insect-fungus relationships, which can be neutral, mutually beneficial, exploitative, or antagonistic. Some relationships are merely opportunistic, while others are co-evolved and have become obligatory. Direct mycophagy, or fungivory, occurs when insects preferentially select fungi as a food source. Alternatively, many fungi require insects as a food source and become pathogens. Insects that feed on plants often encounter fungi that either live within the plant as endophytes or in association with plant tissues, resulting in an indirect effect on insect fitness. Often, insects are the vehicle by which fungi gain ingress into a plant or disperse throughout a habitat.
