Which type of bee is recognized for making propolis stores?

Caucasian bees are well-known for their propensity to collect and use propolis, which they gather from tree buds and other plant sources. Propolis is a resin-like material that bees mix with wax to seal and protect their hives. This substance has antimicrobial properties and contributes to hive sanitation by helping to prevent the growth of harmful bacteria and fungi.

While other bee types may have varying abilities to collect propolis, Caucasian bees are particularly noted for their effective propolis foraging behavior, making them a popular choice among beekeepers who value strong hive health and disease resistance. This characteristic sets them apart from the other types listed, which either do not focus on propolis collection as much or are known for other traits.
