Apis mellifera capensis

Definition

A subspecies of the western honey bee endemic to the Western Cape region of South Africa, distinguished by its unique thelytokous parthenogenesis—unfertilized eggs can develop into diploid females—enabling workers to produce fertile offspring and occasionally requeen colonies. This trait underlies its invasive potential when introduced outside its native range.

Etymology

Latin apis 'bee'; mellifera 'honey-bearing'; capensis 'of the Cape'

Example

In South African beekeeping, Apis mellifera capensis workers can parasitize colonies of other honey bee subspecies by entering as drifters and activating their ovaries to produce diploid female offspring, a behavior that has caused significant management challenges when capensis bees spread into regions dominated by Apis mellifera scutellata.

Synonyms

• Cape honey bee
• Cape bee

Related Terms

• Apis mellifera
• Apis mellifera scutellata
• thelytoky
• Parthenogenesis
• Subspecies
• worker policing
• social parasitism

Usage Notes

The subspecies designation is sometimes disputed in literature; some authors treat capensis as a distinct species or a race. Thelytoky is facultative, not obligate—mated queens produce normal sexual offspring. The hybrid zone with neighboring subspecies, particularly scutellata, is active and economically significant due to defensive behavior differences.
