What is a common substitute for nectar that is used in beekeeping?

High Fructose Corn Syrup is commonly used in beekeeping as a substitute for nectar due to its high sugar concentration and similar composition, making it a suitable energy source for bees. It can be easily transported, stored, and mixed with water to provide a feeding solution that mimics the natural carbohydrates found in nectar. This is particularly beneficial during times when natural nectar sources are scarce, such as during dearth periods or early in the spring before flowers bloom. Additionally, High Fructose Corn Syrup is economical and can be produced in large quantities, ensuring that beekeepers have a reliable resource to support their colonies' nutritional needs.
