Doublebanded Carpenter Bee
Xylocopa caffra
Doublebanded Carpenter Bee
The Banded Carpenter Bee is a stout, long-tongued insect. They're called carpenter bees because they drill into plant stems, branches and timber to make their nests- so they may be pests in some cases. They'll use sawdust particles to build cell-partitions within the drilled tunnels.
These bees do well in a variety of habitats, including fynbos, succulent karoo, farmland, marshland, coastal bush, woodlands, and of course, they're frequent garden visitors, too!
They are typically solitary, meaning they care for broods alone. They're specialist pollinators of many vegetable and fruit crops, as well as indigenous plants.
They're able to perform something known as 'buzz pollination', a behaviour which enables them to collect pollen from plants whose pollen remains firmly attached to the anthers.
Traits

Pollinator of many indigenous plants and agricultural crops.

They may drill holes in plants and built wooden structures.
Appearance
Adults: The female is black with two bands of yellow (or white) hairs, one on the thorax and on on the abdomen. The male is entirely yellow. The wings are tinted black. Sometimes they house small, red-brown mites on the abdomen.
Larvae and Eggs: Gardeners rarely see these because they spend the life stage developing in the nest or burrow.
Symptoms
They may excavate in tree trunks, in dead wood, bamboo, or structural timbers.
They may hollow out stem structures of Aloe and Agave.
Some have been known to tunnel into wooden garden furniture!

Biological treatment
Xylocopa caffra is a brilliant garden pollinator; it's advised to tolerate them wherever possible.
Not only will they help increase flowering and yields, but they're also important pollinators of indigenous plants, too! You can attract them into your garden by leaving stacks of old timber, deadwood and branches. They enjoy the nectar and pollen of pink, purple, white and yellow open-petaled flowers.
