Just found this:
BeeWeaver package bees are 3 pounds of bees with a young, mated queen. The beekeeper can put them in any type of hive (Top Bar Hive, Langstroth Hive, Observation Hive…). Package bees must be fed sugar syrup as soon as they are hived until the bees stop feeding on the syrup because they are building from scratch. BeeWeaver package bees can be picked up from any of our pick-up locations in Texas or shipped directly to the customer via UPS. BeeWeaver package bees are less expensive then the BeeWeaver nucs, but they are not as established as a nuc and do not have brood, so package bees require more time before baby bees begin to emerge to replenish older foragers.
BeeWeaver nucs are 4 deep frames of bees, brood, honey, & pollen. A young, mated queen is laying in the nuc. The beekeeper can put them in a deep hive body of a Langstroth hive – the combs from a nuc will not fit in a top-bar hive unless you cut them into pieces. The BeeWeaver nuc also includes an in-hive feeder and small hive beetle trap. Our nucs are splits (also called divides or increase) made from established colonies. Four combs from an existing colony or colonies are removed from the original hive and placed in a plastic nuc box with a lid for transport, and a new queen is introduced into the nuc. The nuc will build up quickly if fed, and is less vulnerable to starving, absconding, or robbing than a package. The nuc is more expensive then a BeeWeaver package, and it is available only by pick up at our shop or other Texas locations.
