Anthidium manicatum is a type of solitary bee that is commonly found in Europe, Asia, and North America. They are active during the summer months and are known for their distinctive behavior of “carding” wool from plants to use in their nests. The male bees are particularly aggressive, defending their territory and the flowers they feed on from other insects, including other males of their own species.

Life span & Size of Anthidium manicatum
The lifespan of individual bees can vary depending on various factors such as food availability, predation, and environmental conditions.
In terms of size, the Anthidium manicatum is a relatively small bee, with females measuring around 12 to 14 millimeters in length and males measuring around 10 to 13 millimeters in length. They are robust and have a black and yellow striped body with a distinct, horn-like projection on their head.
Despite their small size, Anthidium are important pollinators of many different types of plants and play a crucial role in maintaining the health and diversity of ecosystems.
Habitat and Nesting
Anthidium manicatum prefers to nest in hollow stems or other small cavities, such as abandoned beetle burrows or man-made nesting boxes. The female bee collects plant fibers, such as hairs from leaves or stems, and uses them to construct the walls of her nest. The nest is divided into several cells, each of which contains a single egg and a supply of pollen and nectar for the developing larva.
Sting
Anthidium manicatum is not typically aggressive towards humans and is not considered a serious threat. However, like all bees, they are capable of stinging if provoked or threatened.
Anthidium manicatum Reproduction
- Mating: Adult males emerge from their cocoons earlier than females and wait near nesting sites for females to emerge. Once a female appears, several males may compete for her attention. The male bee grasps the female by her thorax and copulates with her in mid-air.
- Egg-laying: Once the nesting cavity is lined, the female bee lays a single egg on top of the fiber lining. She then collects more plant fibers and uses them to form a cell around the egg, sealing it in. She repeats this process until the nesting cavity is full.
- Provisioning: Before sealing each cell, the female bee collects nectar and pollen from flowers and packs it into the cell along with the egg. This mixture of nectar and pollen, called “bee bread,” provides nutrition for the developing larva.

How do Anthidium manicatum survive in winter?
In colder climates, Anthidium overwinters as a larva inside its nest. The adult bees die off in the fall, and the larvae remain dormant until the following spring, when they pupate and emerge as adults.
| Characteristic | Male | Female |
| Body size | Smaller | Larger |
| Antennae | Longer and more curved | Shorter and less curved |
| Abdomen | More pointed | More rounded |
| Sex organs | Have external genitalia visible at the tip of the abdomen | Have internal genitalia |
| Behaviors | Patrol nest sites and mate with females | Collect pollen and nectar and construct nests |
Difference between Male & Female Anthidium Bees.
Male and female Anthidium manicatum bees have distinct physical and behavioral differences. Males are typically smaller in size than females, with longer and more curved antennae, and a more pointed abdomen. They have external genitalia visible at the tip of their abdomen and spend their time patrolling nest sites in search of potential mates.
Females, on the other hand, are larger in size with shorter and less curved antennae, and a more rounded abdomen. They have internal genitalia and spend their time collecting pollen and nectar and constructing nests using plant fibers.
Overall, the differences between male and female Anthidium bees reflect their distinct roles in the reproductive process and the construction of their nests.
FAQS
What is the lifespan of Anthidium manicatum bees?
The lifespan of Manicatum bees is typically one year

Anthidium manicatum bees play an important role in pollinating a variety of flowering plants, which helps to maintain the health and diversity of ecosystems.
How do humans interact with Anthidium bees?
Humans can benefit from Anthidium manicatum bees by encouraging their presence in gardens and agricultural areas, but they can also pose a risk to the bees through pesticide use and habitat destruction.
Are manicatum bees considered endangered or threatened?
Anthidum manicatum bees are not currently considered endangered or threatened, but their populations may be declining in some regions due to habitat loss and pesticide exposure.
Summary
Anthidium manicatums is a fascinating and important species of bee that plays an important role in pollinating our crops and sustaining our ecosystems. Their distinctive behavior and aggressive defense of their territory make them an interesting subject for study, and their use of wool in their nests is a unique adaptation that sets them apart from other bees.
