# Cactus chimney bees (*Diadasia australis*) Cactus chimney bees are small, fuzzy bees that love to visit flowers. They are great pollinators and help plants grow by spreading pollen. These bees make their homes in special tubes in the ground. - **Category:** [Insects](https://www.snappit.app/explore/categories/insect) - **Rarity:** Common - **Danger:** 1/5 · Very low - **Habitat:** Desert ![Cactus chimney bees](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Diadasia_australis%252C_M%252C_back%252C_Penningtion%252C_SD_2015-11-12-10.13.48_ZS_PMax_UDR_%2822758992009%29.jpg&width=800) Photo: USGS Bee Inventory and Monitoring Lab from Beltsville, Maryland, USA, Public domain · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Diadasia_australis%252C_M%252C_back%252C_Penningtion%252C_SD_2015-11-12-10.13.48_ZS_PMax_UDR_%2822758992009%29.jpg) ## Appearance The Cactus chimney bee has a fuzzy, stout body, typically greyish-tan with lighter, thin bands across its abdomen. It possesses large, dark eyes and dense, specialized hairs on its hind legs for pollen collection. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Arthropoda - **Class:** Insecta - **Order:** Hymenoptera - **Family:** Apidae - **Genus:** Diadasia ## Interesting facts - Baby cactus bees grow up eating a special "bee bread" their mommies make! - Female bees often dig their individual nests very close, creating "bee towns"! - These super picky bees only eat pollen and nectar from cacti! - They're called "chimney bees" because some build turret-like nest entrances! ## Special abilities - **Pollen Basket Legs:** Cactus chimney bees have specialized, dense hairs on their hind legs that help them efficiently scoop and carry sticky cactus pollen. - **Earth Excavators:** Cactus chimney bees can dig intricate underground burrows to create safe, individual nurseries for their developing young. - **Buzz Pollinators:** Cactus chimney bees can vibrate their flight muscles to shake stubborn pollen loose from certain flowers that hide it away. ## Measurements & details - **Wingspan:** 20-30 mm - **Size:** 10-15 mm - **Lifespan:** 20-40 days - **Flight Speed:** 15-25 km/h - **Leg Count:** 6 ## Diet & Feeding They sip sweet nectar and gather protein-rich pollen exclusively from desert cacti. - **Age differences:** Larvae consume 'bee bread' (pollen and nectar paste), while adults feed on liquid nectar and pollen. - **Primary Foods:** Cactus pollen, Cactus nectar, Desert flower pollen, Desert flower nectar - **Foraging Method:** Foraging ## Ecological connections - **Pollinates:** Mojave prickly pear (*Opuntia phaeacantha*) — Helps this cactus produce fruits and seeds. - **Pollinates:** [Engelmann's hedgehog cactus](https://www.snappit.app/explore/engelmanns-hedgehog-cactus) (*Echinocereus engelmannii*) — Crucial for the reproduction of this desert cactus. - **Eaten by:** [Eastern fence lizard](https://www.snappit.app/explore/eastern-fence-lizard) (*Sceloporus undulatus*) — Lizards sometimes prey on foraging bees near flowers. - **Depends on:** [Saguaro cactus](https://www.snappit.app/explore/saguaro-cactus) (*Carnegiea gigantea*) — Requires cactus species for its specialized pollen and nectar diet. ## Traits - [Furry](https://www.snappit.app/explore/traits/furry): Furry describes animals possessing a dense covering of soft hair or fur. - [Social](https://www.snappit.app/explore/traits/social): Social animals live in organized groups, cooperating for survival benefits such as foraging, defense, and raising offspring. - [Herbivorous](https://www.snappit.app/explore/traits/herbivorous): This trait characterizes organisms whose diet consists entirely or primarily of plant material. - [Pollinator Magnet](https://www.snappit.app/explore/traits/pollinator-magnet): Describes plants that are particularly attractive and beneficial to a wide range of pollinating organisms. - [Desert](https://www.snappit.app/explore/traits/desert): Desert habitats are arid regions characterized by extremely low precipitation and often extreme temperatures, supporting specialized flora and fauna. - [Diurnal](https://www.snappit.app/explore/traits/diurnal): Diurnal animals are primarily active during daylight hours, typically resting or sleeping at night. - [Keystone Species](https://www.snappit.app/explore/traits/keystone-species): Describes a species whose presence and role have a disproportionately large effect on its environment. - [Pollinator](https://www.snappit.app/explore/traits/pollinator): Describes organisms that transfer pollen, enabling the fertilization and reproduction of plants. ## Collections - [Insects](https://www.snappit.app/explore/collections/insects) ## Safety **Danger:** 1/5 · Very low Be gentle and watch from a distance when you see bees.
