Thyreus denolli is an African species of kleptoparisitic bee. It belongs to the tribe Melectini and to the genus Thyreus , the members of which are often referred to as 'Cuckoo bees', due to their parasitic behaviour. It is one of the most distinctive Thyreus bees in Cape Verde. [1]

History

The species was first described in 2012, and was named after the Genoese navigator António de Noli, who after being exiled from his home country discovered the Cape Verde Islands around 1456 while he was working for Portugal. [1]

T. denolii, along with the other species of Thyreus found in Cape Verde, closely resembles the species Thyreus hohmanni, as well as the more widespread Thyreus ramosus'. T. hohmanni is endemic to the Canary Islands, another macronesian archipelago. It is thus possible that the Thyreus bees of Cape Verde came from the Canary Islands, and separated into separate species across the Cape Verde islands. Similarly, it is possible that all endemic Thyreus species in the macronesian share a nearest common ancestor within populations of Thyreus ramosus. [1]

Thyreus denolli has been recorded in the islands of Sal, Boa Vista, Santiago, and possibly São Nicolau, in Cape Verde. [1] [2] It is one of four species of Thyreus bees in the area, the other three being Thyreus batelkai , Thyreus schwarzi , and Thyreus aistleitneri. [1]

Description

Despite their relative isolation from each other, the species of T. denolii across Sal, Boavista, and Santiago do not seem to show any significant difference in appearance or morphology.

The female is approximately 8.1–10.6mm long, while the male is a little smaller, with a total body length of approximately 7.5–9.9 mm. The heads of the males are approximately 2.7mm long and 3.5mm wide. The female's head is about 3.2 mm long and 3.9 mm wide.

Like all members of its genus, T. denolli has brightly contrasting coloured patterns on its body. The males can be distinguished from other species of Thyreus in the region by its sixth metasomal tergum (that is, the sixth segment of the posterior part of its body). From the side, the white markings on this segment are usually the same size as those on the fourth and fifth terga. In the female, from the side, the white patches on the fifth tergum are the same size as those on the fourth and third terga. [1]

From the front the faces of both sexes very similar to the other members of Thyreus on the island. In the males, the distance between the two eyes is 1.8mm at the top of the eyes and 1.3mm at the bottom. In the females, the distance between the eyes is about 1.9mm at the top and 1.3mm at the bottom. [1]

Both sexes are covered in black or dark brownish-grey pubescence (short hairs) over most of the body. However, parts of the face, legs, and the mesosoma (the middle section of the body) are covered with white, feathery hairs instead. [1]

Breeding and parasitism

The primary hosts of T. denolii and the other three members of Thyreus in Cape Verde are bees in the genus Amegilla, with which it is commonly associated in the field. [1] If the various populations of T. denolli across the islands are indeed separate species, then it is parasitic on three separate species of Amagilla.

Being a member of Melectini , T. denolii is a kleptoparasitic insect. The females of this tribe lay their eggs in the nest of their host, and their larvae use the resources and stored food provided by the host, at the expense of the host's young. [3]

Cuckoo bee

The term cuckoo bee is used for a variety of different bee lineages which have evolved the kleptoparasitic behaviour of laying their eggs in the nests of other bees, reminiscent of the behavior of cuckoo birds. The name is perhaps best applied to the apid subfamily Nomadinae, but is commonly used in Europe to mean bumblebees Bombus subgenus Psithyrus. Females of cuckoo bees are easy to recognize in almost all cases, as they lack pollen collecting structures and do not construct their own nests. They often have reduced body hair, abnormally thick and/or heavily sculptured exoskeleton, and saber-like mandibles, although this is not universally true; other less visible changes are also common.

<i>Nomada</i> Genus of bees

With over 850 species, the genus Nomada is one of the largest genera in the family Apidae, and the largest genus of kleptoparasitic "cuckoo bees." Kleptoparasitic bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected. The name "Nomada" is derived from the Greek word nomas, meaning "roaming" or "wandering."

Corda, Ribeira Grande Settlement in Santo Antão, Cape Verde

Corda is a settlement in the island of Santo Antão, Cape Verde. It is part of the municipality Ribeira Grande. It is situated in the mountainous interior of the island at about 1,000 meters elevation, 13 km north of the island capital Porto Novo. Corda consists of several villages, including Chã de Corda and Esponjeiro. The national road from Porto Novo to Ribeira Grande (EN1-SA01) passes through Corda. The crater of Cova lies 4 km to the southeast. Corda lies in the Cova-Paul-Ribeira da Torre Natural Park.

Wildlife of Cape Verde

The wildlife of Cape Verde is spread over its archipelago of ten islands and three islets, which all have parks under their jurisdiction by decree promulgated by the Cape Verde government. Located off the west coast of Africa, the total land area of the island nation is 4,564 square kilometres (1,762 sq mi). The wildlife consists of many tropical dry forest and shrub land, endemic flora and fauna, and rare breeding seabirds and plants, which are unique to this group of islands.

<i>Bombus vestalis</i> Species of bee

Bombus vestalis, the vestal cuckoo bumblebee, is a species of cuckoo bumblebee that lives in most of Europe, as well as North Africa and western Asia. It is a brood parasite that takes over the nests of other bee species. Its primary host is Bombus terrestris. After its initial classification as Psithyrus vestalis, this bumblebee recently was reclassified into the genus Bombus, subgenus Psithyrus.

<i>Bombus bohemicus</i> Species of bee

Bombus bohemicus, also known as the gypsy's cuckoo bumblebee, is a species of socially parasitic cuckoo bumblebee found in most of Europe with the exception of the southern Iberian Peninsula and Iceland. B. bohemicus practices inquilinism, or brood parasitism, of other bumblebee species. B. bohemicus is a generalist parasite, successfully invading several species from genus Bombus. The invading queen mimics the host nest's chemical signals, allowing her to assume a reproductively dominant role as well as manipulation of host worker fertility and behavior.

<i>Bombus suckleyi</i> Species of bee

Bombus suckleyi is a species of bumblebee known commonly as Suckley's cuckoo bumblebee, named after biologist George Suckley. Suckley's bumble bee is a generalist pollinator and represents a rare group of obligate, parasitic bumble bees. Suckley's bumble bee is a social-parasite because it invades the nests of the host bumble bees, including the western bumble bee, and relies on host species workers to provision its larvae. It is native to northwestern North America, including Alaska and parts of western and central Canada and the western United States.

<i>Thyreus</i> Genus of bees

Thyreus is an Old World genus of bees, one of many that are commonly known as cuckoo bees, and are cleptoparasites of other species of bees, mostly in the genus Amegilla. They all have strongly contrasting patterns of coloration - three species from the Sydney region, Thyreus nitidulus, T. lugubris, and T. caeruleopunctatus are bright blue and black.

<i>Thyreus nitidulus</i> Species of bee

Thyreus nitidulus, commonly known as the neon cuckoo bee, is a parasitic bee of the genus Thyreus, called cuckoo bees. It is a stocky bee, notable for its brilliant metallic blue- and black-banded colors.

<i>Dolichovespula adulterina</i> Species of wasp

Dolichovespula adulterina is a species of parasitic social wasp found in the Palearctic region. D. adulterina feeds on a variety of foods, including insects, spiders, arthropods, meat, molluscs, fruit, nectar, and larval secretions. D. adulterina was formerly considered to be synonymous with D. arctica from the Holarctic region, but more recent research indicates that D. arctica is a separate species.

<i>Vespula austriaca</i> Species of wasp

Vespula austriaca is an obligate parasitic wasp, parasitizing the nests of other species in the genus Vespula in the Old World. Its common host species include V. rufa in Europe, Japan, and East Siberia.V. austriaca wasps pollinate orchids.

<i>Bombus flavifrons</i> Species of bee

Bombus flavifrons, the yellow-fronted bumble bee or yellowhead bumblebee, is a species of bumblebee. It is native to North America, where it is distributed across much of Canada, Alaska, and the western contiguous United States.

<i>Sphecodopsis</i> Genus of bees

Sphecodopsis is a genus of cleptoparasitic "cuckoo" bees in the family Apidae. Endemic to southern Africa, the wasp-like bees of this genus are generally small, varying from 3.9 to 9 mm in length, and mostly black, with orange-ish or reddish colouring of the metasoma in some of the species. The bee genus Scrapter is recognised as a host for the cleptoparasitic life cycle of some Sphecodopsis, but further data regarding preferred hosts is not available for most of the species.

<i>Megachile campanulae</i> Species of bee

Megachile campanulae, known as the bellflower resin bee, is a species of bee in the family Megachilidae. Described in 1903, these solitary bees are native to eastern North America. Studies in 2013 placed them among the first insect species to use synthetic materials for making nests. They are considered mason bees, which is a common descriptor of bees in several families, including Megachilidae. Within the genus Megachile, frequently also referred to as leafcutter bees, M. campanulae is a member of the subgenus Chelostomoides, which do not construct nests from cut leaves, but rather from plant resins and other materials. Females lay eggs in nests constructed with individual cell compartments for each egg. Once hatched, the eggs progress through larval stages and subsequently will overwinter as pupae. The bees are susceptible to parasitism from several other bee species, which act as brood parasites. They are medium-sized bees and the female adults are typically larger than the males. They are important pollinators of numerous native plant species throughout their range.

<i>Coelioxys sodalis</i> Species of bee

Coelioxys sodalis is a bee from the family Megachilidae, one of numerous kleptoparasitic bees in the tribe Megachilini. Members of the genus Coelioxys exhibit kleptoparasitic behavior in that they lay their eggs in the nests of other bees, typically those of the related genus Megachile. As this behavior is similar to that of cuckoos, such bees are referred to as cuckoo bees. These host-parasite relationships are complex Host insects of the brood parasite C. sodalis include Megachile melanophaea, M. texana, and M. rotundata.

<i>Coelioxys</i> Genus of bees

Coelioxys, common name leaf-cutting cuckoo bees or sharp-tailed bees , is a genus of solitary kleptoparasitic or brood parasitic bees, belonging to the family Megachilidae.

<i>Chrysis ignita</i> Species of wasp

Chrysis ignita, also known as the ruby-tailed wasp, is a species of cuckoo wasps. Cuckoo wasps are kleptoparasites – they lay their eggs in the nests of other wasp species and their young consume the eggs or larva of the host wasp for sustenance. These wasps have a number of adaptions which have evolved to equip them for their life cycle. Chrysis ignita parasitize mason bees in particular. Ruby-tailed wasps have metallic, armored bodies, and can roll up into balls to protect themselves from harm when infiltrating the nests of host bees and wasps. Unlike most other Hymenopterans, cuckoo wasps cannot sting. Chrysis ignita is found across the European continent.

Thyreus lugubris Species of bee

Thyreus lugubris, is a species of Australian native bee belonging to the family Apidae subfamily Apinae.

<i>Lasioglossum leucozonium</i> Species of bee

Lasioglossum leucozonium, also known as Lasioglossum similis, is a widespread solitary sweat bee found in North America, Europe, Asia, and parts of northern Africa. While now a common bee in North America, population genetic analysis has shown that it is actually an introduced species in this region. This population was most likely founded by a single female bee.

<i>Bombus ignitus</i> Species of bee

Bombus ignitus is a species of bumblebee in the family Apidae. It is mainly distributed in Eastern Asia, commonly found in China, Japan, and Korea. It is used in China and Japan commercially as a pollinator. B. ignitus is a eusocial insect with a queen that is monandrous - mating with only one male in the late summer before hibernating until the following spring. It builds its nest out of a mass of pollen and lays its eggs after completion. Due to numerous conflicts between queens and fertile workers, some surviving queens are badly injured, described by some as living corpses.
