The Gypsy Cuckoo Bumblebee (Bombus bohemicus) is an intriguing and rare species of parasitic bumblebee. Renowned for its unique reproductive behavior and reliance on host species, this bumblebee plays a vital role in our ecosystem. However, its declining numbers highlight the need for conservation efforts. Despite its challenges, this species continues to inspire curiosity among scientists and nature enthusiasts.
Gypsy Cuckoo Bumblebee
- Common Name: Gypsy Cuckoo Bumblebee
- Latin Name: Bombus bohemicus
- Size: 15-20 mm for queens, 11-17 mm for males
- Location: Found across Europe, Asia, and North America
- Active Months: April to September (in the UK)
- Habitat: Woodlands, meadows, and gardens near host bumblebee colonies
- Nesting Behaviour: Parasitic; invades the nests of host bumblebees, such as the Buff-tailed Bumblebee (Bombus terrestris)
- Social Behaviour: Solitary
- Flora & Fauna: Relies on host species for survival; indirectly benefits from the host’s pollen and nectar collection
- UK Status: Declining; considered a conservation concern
Recognising the Gypsy Cuckoo Bumblebee
Identifying the Bombus bohemicus can be challenging due to its similarity to its host species. However, there are distinct features to look for:
- Appearance: Females display a bold yellow band at the front of the thorax and a fainter band at the back. Both males and females have white tails with faint yellow patches.
- Unique Traits: Unlike most bumblebees, this species lacks pollen baskets on its hind legs and has a more robust body.
Extended Active Season
This species is active from early spring through late summer. Its lifecycle closely aligns with that of its host species, as it relies on host colonies for reproduction.
Supporting the Ecosystem
While parasitic, the Gypsy Cuckoo Bumblebee plays a critical role in maintaining bumblebee diversity. By interacting with its host species, it indirectly supports pollination and contributes to ecosystem health.

Frequently Asked Questions
What is a Gypsy Cuckoo Bumblebee?
The Bombus bohemicus is a parasitic species that invades the nests of other bumblebees to reproduce.
How does the Gypsy Cuckoo Bumblebee reproduce?
Females infiltrate host nests, eliminate the resident queen, and lay eggs that the host workers care for.
What do Gypsy Cuckoo Bumblebees look like?
These bumblebees are robust, with yellow bands on the thorax and a white tail featuring faint yellow patches.
Do Gypsy Cuckoo Bumblebees collect pollen?
No, they rely entirely on host workers to gather pollen and nectar, as they lack pollen baskets.
Are Gypsy Cuckoo Bumblebees endangered?
Yes, their populations are declining due to habitat loss, pesticide use, and a reduction in host species.
How can I help conserve Gypsy Cuckoo Bumblebees?
You can help by planting native flowers, avoiding pesticides, and supporting conservation programs that protect their habitats.
