Taxonomy and phylogeny[edit] This species belongs to the family Megachilidae and the order Hymenoptera, which consists of organisms such as ants, bees and wasps, and the superfamily Apoidea, which is more specific to bees and wasps.[6]


Description and identification[edit] Detail of patterns on the abdomen of a male Anthidium manicatum A female A. manicatum A male A. manicatum Anthidium manicatum is originally an Old World bee. It has a wingspan of approximately 20 millimetres (0.79 in), with a body length of about 11–13 mm (0.43–0.51 in) for females, and 14–17 mm (0.55–0.67 in) for males.[7] The males are substantially larger than females.[1] A. manictum are black and covered with yellow-grey hairs. Their faces and abdomen are covered in yellow spots. Male A. manicatum have a black head and thorax, coated with short yellowish brown hairs. The cheeks below the antennae, a small spot behind each eye, a bilobate spot on the clypeus, and the mandibles (except the apex) are yellow. The wings are dusky in color. The abdomen is black with grey hairs, with a band of brown hairs at each segment’s apex as well as along their lateral margins.[8] This feature distinguishes male A. manicatum from native Anthidium species.[9] There is a yellow spot on each side of the segments except the 7th. A second pair of spots is often seen on the disks of the 4th and 5th segments. There is a spine on each side of the 6th and 7th segments at the apex, the 7th having a third thin spine in the middle. The legs exhibit variegation of yellow and are covered with grey hairs. Female A. manicatum are smaller in size than the males, but have a similar color pattern. The abdominal spots are smaller and the apex is rounded. Female legs are almost completely black, with very small yellow spots.[8] The anterior sides of the tarsal segments of each leg of female A. manicatum have fine, soft and small white-colored hairs. This pilosity occurs in most species of Anthidium in the Western Palearctic region.[10] Male A. manicatum resemble A. maculosum in appearance. The two species have similar spiniform pygidia, as well as largely rounded sixth sterna (although that of A. manicatum is more so).[9]


Distribution and habitat[edit] Anthidium manicatum is found in parts of Europe, Asia, North Africa, and North America. It has also recently been documented in the Canary Islands, and South American countries such as Argentina, Brazil, Paraguay, and Uruguay.[11][12] As of 2006, this species is also now established in New Zealand.[13] This insect was accidentally introduced into the United States from Europe sometime prior to 1963, when it was discovered in New York State.[14] It has since spread from the northeastern U.S. and southeastern Canada across the United States to California, where it was first collected in 2007.[15] This species' tendency to occupy ready-made nesting sites, usually movable objects, allows it to spread to new locations easily.[9] In Europe, this species is normally found in gardens, fields, and meadows in the southern part of Wales and England, but is localized in other places within the United Kingdom,[4] where they can be seen from May to September.[4] A. manicatum is the only species of the genus Anthidium that can be found in England.[16]


Nesting[edit] 'Wooly' trichomes as seen on Stachys byzantina, used by A. manicatum for nest construction. Being a member of the Anthidiini tribe of megachilid bees, A. manicatum engages in highly elaborate nesting behavior. These bees construct their nests in preexisting cavities, using the trichomes of wooly plants. Female A. manicatum use their mandibles, which are sharply toothed, to remove trichomes from the stems and leaves of various plants. They then roll up the trichomes into a ball and bring them to a preexisting cavity. Inside the cavity, the bees fashion the trichome ball into cells, where they deposit an egg as well as a provisioning mass consisting of nectar and pollen. The female creates several cells in a cavity. Once finished, she seals the entrance to the cavity with a terminal plug, which consists of inorganic and organic materials that she brings to the nest.[17] Females collect "down" from such plants as lamb's ears (Stachys byzantina). They scrape the hairs from the leaves and carry them back to their nests bundled beneath their bodies. There it is used as a lining for their nest cavities.[1][18] Females tend to build their nests at high locations. This may be in order to minimize the nest’s exposure to parasites and predators. This may also be to avoid nest usurpation by other female A. manicatum.[17] Materials[edit] Besides trichomes, other materials used by female A. manicatum for building brood cells include mud, stones, resin, and leaves. Some of the plant materials that are collected are hydrophobic, a feature that may serve an anti-microbial function for the nest. Females smear a plant substrate, plant extrafloral trichome secretions, on brood cells. The primary material used to build the cells are plant hairs, or "wool" (hence the name "wool carder bee"), that is collected from the stems and leaves of plants. Females largely use the hairs of Lamiaceae, especially those of the genus Betonica or Stachys. Additionally, females use specialized hair-like structures on the exterior of their tarsi to absorb the secretions of the plant hairs to apply onto the brood cells. These secretions are obtained from different species, such as Anthirrinum, Crepis, and Pelargonium.[19]


Behavior[edit] Anthidium manicatum asleep in a flower Mating behavior[edit] The mating system of A. manicatum is unlike those of most other bees. Females exhibit polyandry and continuously mate throughout their reproductive life.[20] The interval of time between copulations amongst different males can be as short as 35 seconds in length.[21] Males exhibit resource defense polygyny. A. manicatum display extreme polyandry, which is linked to male territoriality and resource defense of flowering plants. Males claim patches of floral plants, ward off conspecific males and other resource competitors, and mate with the females who forage in their territories. Copulations occur repeatedly and regularly in both sexes. Males that are unable to defend their own territory (usually because of their relatively small size) utilize an alternative ‘sneaking’ tactic. These unfit males receive fewer copulation opportunities than females.[20] Such mating and territorial behavior in bees has also been observed in Anthidiellum notatum, Anthidiellum perplexum, and Anthidium banningense. However, males of the genus Anthidiellum chase away intruders rather than physically attacking them, so their aggressive behavior differs significantly.[22] Resource defense[edit] The territorial mating behavior of male A. manicatum occurs when foraging resources are amassed, allowing for monopolization and defense of territories by individual males.[20] Resource defense, as exhibited by male A. manicatum, has been thought to benefit females by reducing foraging competition for pollen and nectar.[20] The rate a female visits a territory is highly correlated with the number of flowers in that area.[21] If females forage in sites that are being defended by males and the cost of additional matings is low for female members, then male resource defense and female polyandry may coevolve.[20] Male aggression[edit] Male A. manicatum display highly aggressive behavior.[23] Males are highly aggressive towards each other as well as other visitors to the flowers in its territory.[1] In the process of obtaining and defending flowering plant territories, they frequently attack conspecific males and heterospecific pollinators. A. manicatum sometimes lethally injure the pollinators as a result of their aggressiveness.[17] The territorial behavior of males develops after a period of flight without any localization.[23] They will also defend Anthidium manicatum females,[12] although they do harass them by holding them immobile and repeatedly attempting to mate.[2] Late male sperm precedence[edit] Studies show that there appears to be no selection pressure on male A. manicatum to be the first to copulate, and hence no (or very little) selection pressure to emerge before females.[24] This is due to the females' polyandrous behavior, and can also be attributed to a phenomenon called "'Late' male sperm precedence". Patterns of sperm use by the females determine the benefits of resource defense for males. If the female uses only the sperm from her first copulation in a breeding season, then selection will not favor the ‘sit-and-wait’ strategy of resource defense for the males over strategies that are pre-emptive, such as patrolling nest sites. However, if delayed mating can still ensure a high probability of procreating, then the resource defense strategy will be favored.[20] ‘Late male sperm precedence’, or LMSP, is an experimental situation in which two males mate in sequence with a female and the second male will hold paternity of over 50% of the female’s offspring. Although females do have a spermatheca for long-term sperm storage, more recent mates tend to father the brood she produces. This phenomenon might be caused by a variety of mechanisms, including sperm digestion or removal by the female, removal by the next male, or stratification of sperm from different males in the sperm storage organ of the female (i.e. the last sperm in is the first to come out). Studies have shown that A. manicatum males that copulate late in a sequence have a greater than average chance of paternity of the female’s eggs. Late male sperm precedence may have fostered the evolution of resource defense in A. manicatum males.[20]


Sexual dimorphism[edit] Unlike most other species of Hymenoptera, male A. manicatum are larger than females in size, displays male-biased sexual dimorphism. The selection for larger size in males may have resulted due to their aggressive territorial behavior and subsequent differential mating success. Although it does not tear other males apart, the abdominal armature of a male A. manicatum may have been developed due to territorial aggression, rather than for mating purposes.[23] Male size has been found to correlate with mating success. Smaller males will implement alternative mating tactics if they cannot defeat larger males for territory.[17] The mating behavior of male A. manicatum can be determined by relative body size to other conspecific males. Territory owners are larger in size than wanderers, and copulate with females more frequently as well. The number of copulations a male territory owner can achieve varies based on the size of the territory – males with larger territories generally achieve more copulations than those with smaller territories. This difference may be due to the energy expenditure of smaller bees to defend their territory from larger males, the inability of small males to mate on their territory, or female choice of larger males (regardless of territory size).[25] Hence the number of copulations a male obtains is positively correlated with territory quality as well as male size.[20]


Diet and foraging behavior[edit] Anthidium manicatum consumes the pollen from flowers of varying families. They are thus considered to be generalists. They visit garden flowers and weeds preferring blue flowers that have long throats[1] with Old World origins.[1] Both males and females hover near flowers similar to flies in the family Syrphidae.[26]
