help Bombus sylvarum FAQ
Why is Bombus sylvarum called the "shrill carder bee"?
Bombus sylvarum, commonly known as the shrill carder bee, gets its name from the distinctively high-pitched buzzing sound it makes while flying. This audible "shrill" helps entomologists and nature spotters identify the species in the wild.
Where does the shrill carder bee typically build its nests?
The shrill carder bee is a surface-nesting bumblebee that often builds its colonies in tall, dense grasslands or tussocky vegetation. They frequently utilize old mouse nests or simply nest slightly above ground in thick, undisturbed flora.
What is causing the decline of the shrill carder bee in the United Kingdom?
The shrill carder bee has experienced a severe population decline in the UK primarily due to the loss of traditional wildflower meadows and intensive agricultural practices. Because it relies on specific habitats with deep flowers and late-blooming plants, modern land development has heavily fragmented its environment.
What coloration distinguishes the Bombus sylvarum bumblebee?
The shrill carder bee features a distinctive appearance with a greyish-greenish-yellow thorax and a prominent dark band located between the wing bases. Its abdomen is primarily yellow but features distinct black stripes, including a bright orange or tawny tail at the very end.
