Subspecies

Description

Bembecinus tridens can reach a length of 7–11 millimetres (0.28–0.43 in). The body is black and yellow.

Biology

These wasps fly in one generation from early June to late August. The females dig a unicellular nest, though a single female digs 1-8 nests in succession. After an egg is laid in the cell the prey item (various families of Homoptera) is introduced. [2] [3] The species is parasitized by Hedychrum chalybaeum . [4]

Distribution and habitat

This species can be found from Western Europe and North Africa to Japan and China. [5] They are common inhabitants of sandy areas.

<span class="mw-page-title-main">Apocrita</span> Suborder of insects containing wasps, bees, and ants

Apocrita is a suborder of insects in the order Hymenoptera. It includes wasps, bees, and ants, and consists of many families. It contains the most advanced hymenopterans and is distinguished from Symphyta by the narrow "waist" (petiole) formed between the first two segments of the actual abdomen; the first abdominal segment is fused to the thorax, and is called the propodeum. Therefore, it is general practice, when discussing the body of an apocritan in a technical sense, to refer to the mesosoma and metasoma rather than the "thorax" and "abdomen", respectively. The evolution of a constricted waist was an important adaption for the parasitoid lifestyle of the ancestral apocritan, allowing more maneuverability of the female's ovipositor. The ovipositor either extends freely or is retracted, and may be developed into a stinger for both defense and paralyzing prey. Larvae are legless and blind, and either feed inside a host or in a nest cell provisioned by their mothers.

<i>Sphecius speciosus</i> Species of wasp

Sphecius speciosus, often simply referred to as the cicada killer or the cicada hawk, is a large, solitary digger wasp species in the family Crabronidae. The name may be applied to any species of crabronid that preys on cicadas, though in North America, it is typically applied to this species, also referred to as the eastern cicada killer in order to further differentiate it from the multiple other examples of related wasp species. Sometimes, they are called sand hornets, although they are not hornets, which belong to the family Vespidae. This species can be found in the Eastern and Midwest U.S. and southwards into Mexico and Central America. They are so named because they hunt cicadas and provision their nests with them. Cicada killers exert a measure of natural control on cicada populations, and as such, they may directly benefit the deciduous trees upon which the cicadas feed.

The Sphecidae are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps.

<span class="mw-page-title-main">Crabronidae</span> Family of wasps

The Crabronidae are a large paraphyletic group of wasps, including nearly all of the species formerly comprising the now-defunct superfamily Sphecoidea. It collectively includes well over 200 genera, containing well over 9000 species. Crabronids were originally a part of the Sphecidae, but the latter name is now restricted to a separate family based on what was once the subfamily Sphecinae. Several of the subfamilies of the Crabronidae are often treated as families in their own right, as is true of the most recent phylogenies.

<span class="mw-page-title-main">European beewolf</span> Species of wasp

The European beewolf, also known as the bee-killer wasp or the bee-eating philanthus, is a solitary wasp that lives in the Western Palearctic and Afrotropics. Although the adults of the species are herbivores, the species derives its name from the behaviour of the inseminated females, who hunt Western honey bees. The female places several of its paralysed prey together with an egg in a small underground chamber, to serve as food for the wasp larvae. All members of the genus Philanthus hunt various species of bees, but P. triangulum is apparently the only one that specialises in Western honey bees.

<span class="mw-page-title-main">Bembicinae</span> Subfamily of wasps

The Bembicinae comprise a large subfamily of crabronid wasps that includes over 80 genera and over 1800 species which have a worldwide distribution. They excavate nests in the soil, frequently in sandy soils, and store insects of several orders, for example Diptera, Orthoptera, Hemiptera, Lepidoptera and Odonata in the burrows. Some species are kleptoparasites of other Bembicinae. The different subgroups of Bembicinae are each quite distinctive, and rather well-defined, with clear morphological and behavioral differences between them.

<i>Bembix rostrata</i> Species of wasp

Bembix rostrata is a species of sand wasp native to Central Europe. The genus Bembix - of which B. rostrata is among the most distinctive species - has over 340 species worldwide and is found mostly in warm regions with open, sandy soils; Australia and Africa have a particularly rich variety of species.

<i>Philanthus gibbosus</i> Species of wasp

Philanthus gibbosus, the hump-backed beewolf, is a species of bee-hunting wasp and is the most common and widespread member of the genus in North America. P. gibbosus is of the order Hymenoptera and the genus Philanthus. It is native to the Midwestern United States and the western Appalachians. P. gibbosus are often observed to visit flowers and other plants in search of insect prey to feed their young. The prey that P. gibbosus catches is then coated in a layer of pollen and fed to the young wasps.

<span class="mw-page-title-main">Wasp</span> Group of insects

A wasp is any insect of the narrow-waisted suborder Apocrita of the order Hymenoptera which is neither a bee nor an ant; this excludes the broad-waisted sawflies (Symphyta), which look somewhat like wasps, but are in a separate suborder. The wasps do not constitute a clade, a complete natural group with a single ancestor, as bees and ants are deeply nested within the wasps, having evolved from wasp ancestors. Wasps that are members of the clade Aculeata can sting their prey.

<i>Cerceris fumipennis</i>

Cerceris fumipennis, the only species of buprestid-hunting Crabronidae occurring in eastern North America, is found throughout the continental United States east of the Rockies: from Texas and Florida north to Maine, Wyoming, and into Canada. The wasps most often nest in open areas of hard-packed sandy soil surrounded by woody habitat suitable for their buprestid beetle prey.

The thin-waisted social wasps, which typically reside in Neotropical regions from Central to South America, are a small genus of wasps that build nests and live in colonies ranging in size from 1 to 18 members. Microstigmus is widely considered to be the only true eusocial species within the family Crabronidae. Like all Hymenoptera, Microstigmus has an interesting sex determination pattern. Females are 2n (diploid), spawning from eggs that have been fertilized, while males are 1n (haploid) and spawn from unfertilized eggs. Female wasps contain the eggs within their egg sac and have the option of fertilizing them or not, thus having complete control of the gender of their offspring. This wasp genus, part of the suborder Apocrita, is distinguished physically by the narrow waist (petiole) between the end segment of the thorax (mesosoma) and the beginning of the abdomen (metasoma). Specifically, it is in the subgroup of "apoid wasps", those that exhibit social behavior in nesting and foraging. Evidence does exist that in some species social altruism is visible; however, studies on these topics have been limited. The small size and enclosed nest structure makes it difficult to obtain significant data. Although it was originally classified under the Sphecidae family due to its elongated petiole, Microstigmus has been reclassified into the new Crabronidae family.

<i>Sphecius grandis</i> Species of wasp

Sphecius grandis, also called the western cicada killer, is a species of cicada killer wasp (Sphecius). The western species shares the same nesting biology as its fellow species, the eastern cicada killer. S. grandis, like all other species of the genus Sphecius, mainly provides cicadas for its offspring. It forms nest aggregations and mates and broods once in a year, in July and early August. The wasp is on average 3 cm (1 in) to 5 cm (2 in) in length and is amber-yellow with yellow rings on its abdomen.

<i>Ammophila sabulosa</i> Species of wasp

Ammophila sabulosa, the red-banded sand wasp, is a species of the subfamily Ammophilinae of the solitary hunting wasp family Sphecidae, also called digger wasps. Found across Eurasia, the parasitoid wasp is notable for the mass provisioning behaviour of the females, hunting caterpillars mainly on sunny days, paralysing them with a sting, and burying them in a burrow with a single egg. The species is also remarkable for the extent to which females parasitise their own species, either stealing prey from nests of other females to provision their own nests, or in brood parasitism, removing the other female's egg and laying one of her own instead.

<i>Stizus fasciatus</i> Species of wasp

Stizus fasciatus is a species of sand wasps belonging to the family Crabronidae.

<i>Bembecinus</i> Genus of wasps

<i>Ectemnius</i> Genus of insects

Ectemnius is a genus of wasps in the family Crabronidae. 188 species are known. The genus is found around the world but Australia has only two species.

<i>Nysson</i> Genus of wasps

Nysson is a Holarctic genus of kleptoparasitic wasps in the family Crabronidae. Over 100 species are known.

<i>Trypoxylon</i> Genus of wasps

Trypoxylon is a genus of wasps in the family Crabronidae. All Trypoxylon species that have been studied so far are active hunters of spiders, which they paralyse with a venomous sting, to provide as food to their developing larvae. Depending on the species, they will either construct their own nest from mud or find cavities that already exist. These cavities can range from keyholes to nail holes to previously abandoned nests, and are generally sealed with mud to create cells for their larvae.

<i>Pison spinolae</i> Species of insect

Pison spinolae, commonly known as mason wasp, is a solitary wasp of the family Crabronidae, found throughout New Zealand.
