Here's why:
* Toxicity: While not confirmed, some orchids contain toxins or substances that make them unpalatable to most animals.
* Limited Nutritional Value: Orchids don't offer much in the way of nutrition for herbivores. Their leaves and stems are thin and fibrous.
* Defense Mechanisms: Orchids are known for their unique and often intricate blooms that attract pollinators, but they don't have strong physical defenses against herbivores.
While animals might occasionally nibble on a Western prairie fringed orchid, it's not considered a regular food source. The focus of this orchid's survival lies in attracting pollinators for reproduction, not in avoiding being eaten.
