Discover seven rare North East bees you could find in your own garden
The North East is in a position of flux, being at the northern edge of the range of many species and the southern edge of some northern species. Changes in climate, land use and farming practices result in variations to species assemblages. Though a number of the species mentioned are rare in the North East, many are not considered rare in the rest of the UK. Sparse species, those with a thin distribution, can usually be found only by chance, whereas those with restricted distribution are more accessible with some research as to timing and site.
A small solitary bee of heaths and moorlands, widely distributed thought UK, but sparse everywhere. There are only a few scattered records in the North East, but they include the area of Low Force on the Tees, where they nest in a small but dense aggregation. Females take pollen solely from tormentil, though other flowers are visited for nectar.
A small black, yellow and white or peach banded bumblebee, very variable in colour. Distributed throughout the UK but restricted to upland areas of late flower-rich grasslands and moor. The queens are not seen before June, with males emerging into September. Nests are underground in old rodent holes and the species can be found at sites in the upper reaches of the Tyne, Tees, and Wear. A full account of the status of the Broken-belted Bumblebee in the North east can be found in The Bumblebees of North East England.
The Northern Mining Bee is unusual in being a solitary bee with a northern distribution, which extends south to North-East Yorkshire. A rare species scattered over much of Scotland, with a few recent records in the North East. One of the smaller Andrena species, associated with sallow, on the wing from March to June and requiring bare ground for nesting.
A common bee in the south but with no records in Co. Durham or South Northumberland, it has reached the Alnwick coastal area, with five records since 2011. One of the earliest species to emerge in spring it is often mistaken for a small bumblebee, with a fast darting and hovering flight. It exhibits sexual dimorphism, the males being gingery brown with feathery hairs on legs and feet, and the females all black with orange scopa on hind legs. Nests are made in soft mortar, cob walls or cliff faces. A frequent visitor to lungwort, dead-nettle and comfrey, it flies between March and June.
A robust, distinctive bee with yellow spots down each side of the abdomen. Females comb hair fibres from plants such as lamb’s-ear as nest material. Males are very territorial and defend flowers for females from all other insects, and can kill intruders by crushing them. In return females allow males to mate (the only bee where females mate more than once). On the wing from May to August, they nest in hollow stems, dead wood and bee hotels. Still a rare bee in the North East, with one record from each of Wylam (South Northumberland), Berwick and Co. Durham, this species is extending its distribution northwards.
A new arrival to the UK in 2001 and continuing to spread rapidly north. An autumn species, with males emerging in August and persisting into November. As the names suggests, the main food source is ivy. Just bigger than a honeybee with ginger thorax and distinct yellow/orange striped abdomen, they nest in large and densely packed numbers in soft banks and cliffs. Mating occurs as soon as females emerge and can be quite frenzied with a number of males competing for females in ‘mating balls’. Recorded at two sites, Whitburn and Saltburn.
A cuckoo of Red-tailed Bumblebee Bombus lapidarius. Both bees are black with red tails, though the cuckoo has darker wings and no pollen baskets. Females come out of hibernation in late May and start to search for nests of the host bee. They kill the resident queen, then lay eggs which are tended by the host workers. Though still rare in the North East, this bee has been increasing in numbers and range since 2004.
If you record any of these species in your garden or within your local area please submit your records as part of the North East Bee Hunt. Already, your records are helping increase our collective knowledge of bees in the North East. Every record and every bee species counts so please continue to share your sightings throughout the spring and summer.
