Belong

belong, genus, subordinate official, affiliated

Mnemonic

A flag waves proudly above the hive's entrance. Every bee returning from the fields spots that flag and feels a surge of loyalty: "I Belong here." Without the flag, a bee would wander lost among countless hives. The flag is proof of membership—each bee pledges allegiance to the colony it belongs to.
Additional thoughts
Picture a medieval banner (flag) hanging over a beehive entrance. Bees check the flag's crest before entering—only members allowed. The flag represents the group, the bee represents the individual finding its place within that group.
Quick recall
A bee spots the flag above its hive and knows it belongs there.
