Stingless bees

Definition

A diverse tribe of eusocial bees (Meliponini, family Apidae) characterized by highly reduced, non-functional stingers that cannot be deployed for defense. Despite their name, stingless bees possess vestigial stinger structures; their inability to sting distinguishes them from the related corbiculate tribes Apini (honey bees), Bombini (bumble bees), and Euglossini (orchid bees). They rely instead on alternative defenses including biting, caustic chemical secretions, and nest entrance blocking. Stingless bees are the primary pollinators of many tropical crops and wild plants, and are cultivated for small-scale honey and pollen production (meliponiculture), particularly in Mesoamerica and Southeast Asia.

Etymology

From English stingless (lacking a functional sting) + bees; the scientific name Meliponini derives from Greek meli (honey) and Latin pōnere (to place), referring to their honey-storing behavior.

Example

Species of the genus *Trigona* aggressively defend their nests by releasing sticky, irritating resins at intruders, whereas *Melipona* species typically employ less confrontational strategies such as nest camouflage.

Synonyms

• meliponines
• stingless honey bees

Related Terms

• corbiculate bees
• honey bees
• Bumble bees
• Orchid bees
• meliponiculture
• eusociality
• pollination
• nest defense

Usage Notes

The term is morphologically descriptive rather than phylogenetically absolute: male bees of all species and many females in non-apid families (e.g., Andrenidae, Megachilidae) also lack functional stingers. In formal taxonomy, Meliponini is the tribe name; Meliponinae appears in older literature as a subfamily but is now generally synonymized with Meliponini under Apinae. The common name is widely used in agricultural and conservation contexts, though specialists may prefer 'meliponines' to emphasize the clade.
