Identifying Bees with a Black Dot on Their Back

Post date |

ID tips: Yellow and black bands and an orange tail. Small size. Males have yellow facial hair.

Description: The UK’s smallest bumblebee. Common in gardens and other areas with trees and bushes. The early bumblebee is a key pollinator of summer fruits such as raspberries.

Bees play a vital role in pollinating plants and crops, yet many backyard gardeners struggle to identify the different species that visit their gardens. One distinguishing feature that can help is a black dot on the bee’s back. Let’s explore some of the most common bees marked this way and how to tell them apart.

Bumblebees

Bumblebees are large, fuzzy bees that belong to the genus Bombus. There are over 250 species worldwide, and about 50 species native to North America.

Many bumblebee species have a small black dot or spot centrally located on their thorax (mid-section), This includes

  • The common eastern bumblebee (Bombus impatiens), one of the most prevalent. Females have a yellow band on the first abdominal segment, with the rest black.

  • The brown-belted bumblebee (Bombus griseocollis), which has a brown band between its wings.

  • Cuckoo bumblebees like the rusty-patched bumblebee (Bombus affinis), a critically endangered species.

Carpenter Bees

Carpenter bees in the genus Xylocopa are large, robust bees that drill holes in wood to make their nests. They can be up to an inch long and are often mistaken for bumblebees.

Some species have a distinctive white or yellow dot on the top of their heads. This includes Xylocopa micans and Xylocopa virginica, two types commonly found in North America. The dot is more prominent on males.

Mining Bees

Mining bees belong to the family Andrenidae. They are ground-nesting, solitary bees active in spring.

A few species have light-colored hairs forming a central spot on their backs, such as:

  • The ashy mining bee (Andrena cineraria), which has gray hairs Females are black with gray stripes on the thorax.

  • The tawny mining bee (Andrena fulva), marked by reddish-orange hairs. Females are very furry, males less so.

Leafcutter Bees

Leafcutter bees in the genus Megachile cut pieces of leaves to build their nests. They carry pollen on their abdomen instead of their legs.

Some have black dots surrounded by light-colored hairs, including:

  • Megachile rotundata, the alfalfa leafcutter bee, used commercially for pollination.

  • Megachile petulans, which cuts circles from rose leaves.

How to Identify the Dot

When trying to identify a bee with a black dot, look for the following:

  • Location – The dot is usually on the central thorax, not the head or abdomen. In some cases it may be above the wings.

  • Size – The dot is quite small, around 1-3mm wide. It does not cover the entire thorax.

  • Color – The dot itself is black or dark brown. It may be surrounded by light-colored hairs that form a circle.

  • Texture – The thorax area around the dot has a fuzzy, hairy appearance.

Take note of other markings and the bee’s general size and shape as well. Comparing against photos can help pin down the exact species. With practice, identifying bees in your garden by their distinctive dots and markings will become much easier.

Your continued support has brought about crucial changes to protect bees. These include:

  • A ban on 3 bee-harming neonicotinoid pesticides
  • That’s right, the governments of the UK and Wales made the first nationwide plans for bees.
  • Communities should be encouraged to set up bee-friendly areas that give bees and other pollinating insects better places to eat and stay.

FAQ

What kind of bee has a black spot on its back?

Physical Characteristics. Rusty patched bumble bees range in size within and between castes. All rusty patched bumble bees have a mostly yellow upper thorax, with a black spot or band between the wings that may extend toward the back in a v-shape, resembling a thumb tack.

Do carpenter bees bite or sting people?

The short answer is yes. Female carpenter bees can sting you, although they are very unlikely to do so unless you’re handling them or poking your fingers into their burrows (which is already mentioned above as something you should not do). Male carpenter bees are not equipped with stingers.

Should I get rid of carpenter bees?

Like bumble bees, carpenter bees can be aggressive when disturbed. They can also cause significant damage to wood structures. For this reason, if you find them around your home, you should call IPM Pest and Termite for carpenter bee pest control.

Are black carpenter bees harmful?

While fairly harmless, carpenter bees increase the number of nests over the course of years, causing noticeable damage to wood. They can also create stains with their feces. The sudden appearance of carpenter bees crawling out of wood often frightens people. Females can sting, but will only do so if bothered.

What does a black bee look like?

These bees are black with white hairs covering the thorax and the bottom of the abdomen. Many species have large heads with massive jaws that aid in cutting off leaves. They are very fast flyers and carry pollen on their abdomens.

What are the causes of black dots in the eyes?

Black dots in the eyes, often referred to as “floaters, ” are caused by tiny bits of gel or cells in the vitreous (the jelly-like substance in the eye) casting shadows on the retina. They become more noticeable when looking at bright backgrounds. While generally harmless, the sudden appearance of numerous floaters or flashes of light might signal a retinal tear or detachment, requiring prompt medical attention. If concerned, consult an eye care professional for proper evaluation and guidance.

What does a black and white digger bee look like?

The black and white bee has a furry thorax and head covered in fine yellowish hairs. This digger bee species also has black and white legs. The white banded digger bee measures 0.35” – 0.47” (9 – 12 mm) long. The small black and white striped bee is found throughout Europe and as far east as Japan.

What does a black and white mining bee look like?

The black and white bee has an identifiable shiny black abdomen that can appear bluish in bright light. The furry bees also have two slender segmented antennae and heads covered in whitish-gray hairs. The black male ashy mining bee is entirely covered in gray hairs with a tuft of white hairs on its face.

What does a brown striped sweat bee look like?

The small parallel-striped sweat bee is a brown furrow bee with bands of yellow traversing its chocolatey brown abdomen. Other identifying marks of this sweat bee are its furry orange legs, golden brown head and thorax, and large, brown compound eyes. The brown and yellow bee measures 0.47” to 0.51” (12 – 13 mm).

How do you tell a bee from a wasp?

Bees, on the other hand, try to avoid confrontation with humans unless provoked. Another quick way to tell them apart is to look at their bodies. Wasps tend to be narrow-waisted with smooth, slender bodies, while bees are plumper and hairier, with fuzz covering part or all of their bodies and legs.
