Velvet ants commonly are encountered in arid, sandy areas of Texas. The male and female ants have many distinguishing factors.

In shrews, every time they would get within 1 meter of a velvet ant, the velvet ant would begin stridulating. Visit our Cypermethrin page to learn more and to order. Both males and females are covered by dense, velvety pubescence, hence the name velvet ant. The parasite then develops at the expense of the host, eventually killing it.

The venom that velvet ants inject through their stinger has an unknown composition.

The males and females are so distinct in their morphology that entomologists often find it very hard to determine whether a given male and female belong to the same species, unless they are captured while mating. In South Carolina, they are common from about May through September. COVID-19 Extension Updates and Resources ... More Information », Factsheet | HGIC 2485 | Published: Jan 6, 1998 | Print. The velvet ants come in different colors. Velvet ants avoid predation using the following defense mechanisms; a venomous sting (if female), aposematic coloration, a stridulatory organ in their abdomen, an alarm secretion from their mandibular gland, and a durable exoskeleton.

The sting, though extremely painful, is rarely dangerous. Cypermethrin is a synthetic pyrethroid insecticide that is very safe to humans, pets and wildlife but is very effective against a wide range of insects including ants, fire ants, roaches, spiders and crickets. The mutillid larvae then develop as idiobiont ectoparasitoids, eventually killing their immobile larval/pupal hosts within a week or two. Predation is one of the strongest forces natural selection uses to drive the evolution of an organism’s morphology, physiology, and behavior. [10], The exoskeleton of the velvet ant is remarkably strong. Although some species are strictly nocturnal, females are often active during the day.
Guido Nonveiller (1963) hypothesized the Mutillidae are generally stenothermic and thermophilic; they may not avoid light, but rather are active during temperatures that usually occur only after sunset.

It is commonly mistaken for a member of the true ant family, as the female is wingless.

There she usually lays a single egg on the pupa of the host wasp. [citation needed] This characteristic allows them to successfully invade the nests of their prey and also helps them retain moisture.

Velvet ants exhibit haplodiploid sex determination, as do other members of the superfamily Vespoidea. The Mutillidae are a family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. The exoskeleton of all velvet ants is unusually tough (to the point that some entomologists have reported difficulty piercing them with steel pins when attempting to mount them for display in cabinets). Velvet ants are not ants at all but rather solitary female wasps.

The females are quite large (up to 1/2 inch) ,wingless, very hairy and colored bright orange or red with black in between. Careful removal of the insect to a more desirable location is the control method of choice. Most of the time only one of these wasps is seen at a time, posing no problem. Over 400 species occur in the North American southwest.[4]. Male mutillids fly in search of females; after mating, the female enters a host insect nest, typically a ground-nesting bee or wasp burrow, and deposits one egg near each larva or pupa. Red velvet ants or cow killer ants are a solitary type of ants that don’t create nests and conventional ways of fighting other types of ants just won’t be effective in this particular case. They are known for their extremely painful stings, (the sting of the species Dasymutilla klugii rated a 3 on the Schmidt pain index and lasts up to 30 minutes),[1] hence the common name cow killer or cow ant. It is known that they are parasites of other predominantly ground-nesting bees and wasps.

This sting resulted in the dropping of the ants in both cases and avoidance for the remainder of the trial. These ants parasitize bee and wasp nests.

During all the trials that led to the fracture of a velvet ant’s exoskeleton, a total of 4 times, resulted in the death of that velvet ant within 24 hours. If this document didn’t answer your questions, please contact HGIC at hgic@clemson.edu or 1-888-656-9988.

[5] In some species, the male carries the smaller female aloft while mating, which is also seen in the related family Thynnidae. Females are wingless, ant-like in general appearance, and may be seen scurrying about on the ground. [10] These experiments provide evidence that the aposematic coloration of velvet ants causes their predators to hesitate, acting as a visual defense mechanism. [13] This mechanism is an auditory cue warning predators that are about to attack to stay away. Females of Tricholabiodes thisbe are sometimes active up to two hours before sunset. During these trials, none of the painted mealworms were consumed, while all the control mealworms were consumed immediately.

Most of the velvet ants belonging to the genus Dasymutilla are relatively large (1/2″-1″ in length) and brightly colored. However, different scenarios with shrews have shown that the velvet ant would also stridulate after the shrew attacked it. Velvet ants are rarely plentiful enough to become a nuisance.

They usually remain outdoors, in sandy areas, though they may very infrequently be found in dwellings. The colors make these wasps distinct.
Males are winged, and are not frequently observed by most people. American Mutillidae have eight extensive and distinct mimicry rings making up one of the largest Müllerian mimicry complexes on the planet. Members of the family Myrmosidae, formerly classified as a subfamily of mutillids, also have a distinct pronotum in females, but lack felt lines in both sexes.

These ants parasitize bee and wasp nests.

Velvet ants avoid predation using the following defense mechanisms; a venomous sting (if female), aposematic coloration, a stridulatory organ in their abdomen, an alarm secretion from their mandibular gland, and a durable exoskeleton. They usually remain outdoors, in sandy areas, though they may very infrequently be found in dwellings.

Although not as abundant in the Southeast as in the Southwest, the family is still represented in South Carolina by six different genera and 41 different species. Velvet ants are not ants at all but rather solitary female wasps. This also acts as a warning. Many have brilliant patterns of black with red, yellow, or orange. The aposematic coloration of velvet ants often corresponds to a specific Müllerian mimicry ring consisting of dozens of species. [10] The side-blotched lizard was found dead in its tank 24 hours later. The female velvet ant sting is very painful. [6][7][8] During this coevolution, the prey either being consumed by the predator or escaping has resulted in a plethora of impressive defensive strategies in prey species to improve the likelihood of escape. Due to an extremely tough integument (outer covering), chemical and mechanical control are not very effective. Adult mutillids feed on nectar. Only a few species are known to parasitize other types of hosts[14]; exceptions include the European velvet ant, Mutilla europaea, one of the only species that attacks social bees (e.g., Bombus), and the genus Pappognatha, whose hosts are tree-dwelling orchid bees. Their common name velvet ant refers to their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold. According to one researcher, the painfulness of the sting of Dasymutilla klugii outscored 58 other species of stinging insects tested; the only species this researcher rated as having a more painful sting were the Paraponera clavata (bullet ant), Synoeca septentrionalis (warrior wasp), Pepsis spp. [13] As well as being durable, the exoskeleton is also round, making it more difficult for predators to pierce it with attempted stings or bites. The species ranges from Connecticut to Missouri in the north and Florida to Texas in the south.. Due to an extremely tough integument (outer covering), chemical and mechanical control are not very effective.

As is the case for all Aculeates, only female mutillids are capable of inflicting a sting.

Although the winged males are harmless, the wingless females can inflict a severe sting S one to be avoided. Females lay their eggs individually upon the pupae or prepupae of their host. Velvet ants may be seen during the warm periods of the year. Velvet ants are also well known for their very painful sting, so it is better not to provoke them.

Use pesticides only according to the directions on the label. Male velvet ants look more like wasps because they have wings, but they don’t have stingers.

The stinger is a modified female organ called an ovipositor, which is unusually long and maneuverable in mutillids.

The females are quite large (up to 1/2 inch) ,wingless, very hairy and colored bright orange or red with black in between. Velvet ants are rarely plentiful enough to become a nuisance. Information on the biology of velvet ants is incomplete. Finding a suitable nest, the velvet ant chews her way into it. In both sexes, a structure called a stridulitrum on the metasoma is used to produce a squeaking or chirping sound when alarmed.
