Dasymutilla Stevensii
''Dasymutilla stevensi'' is a species of velvet ant native to North America. This species is not common but is known from the drylands of the continent from North Dakota south to Guanajuato. The species is named for his colleague O. A. Stevens who collected the type species in Medora, North Dakota Medora (, ) is a city in Billings County, North Dakota, United States. The only incorporated place in Billings County, it is also the county seat. Much of the surrounding area is part of either Little Missouri National Grassland or Theodore Roo ....

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Velvet Ant
Velvet ants (Mutillidae) are a family (biology), family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. Their common name velvet ant refers to their resemblance to an ant, and their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold. Their bright colors serve as aposematic signals. They are known for their extremely painful stinger, stings, (the sting of the species ''Dasymutilla klugii'' rated a 3 on the Schmidt sting pain index, Schmidt pain index and lasts up to 30 minutes), and has resulted in the common name "cow killer" or "cow ant" being applied to the species ''Dasymutilla occidentalis.'' However, mutillids are not aggressive and sting only in defense. In addition, the actual toxicity of their venom is much lower than that of honey bees or harvester ants. Unlike true ants, they are solitary, and lack complex social systems. Distribution Mutillidae can be found worldwide w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medora, North Dakota
Medora (, ) is a city in Billings County, North Dakota, United States. The only incorporated place in Billings County, it is also the county seat. Much of the surrounding area is part of either Little Missouri National Grassland or Theodore Roosevelt National Park. The population was 121 at the 2020 census and was estimated to be 181 in 2025. It is part of the Dickinson Micropolitan Statistical Area. Medora is home to the South unit of Theodore Roosevelt National Park, and Home to Sully Creek State Park, and to the Seasonal Medora Musical. History Medora was founded in 1883 along the transcontinental rail line of the Northern Pacific Railway by French nobleman Marquis de Mores, who named the city after his wife Medora von Hoffman. Marquis de Mores wanted to ship refrigerated meat to Chicago via the railroad. He built a meat packing plant for this purpose and a house named the Chateau de Mores, which is now a museum. In the evening of April 7, 1903, President Theodore ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Described In 1928
Insects (from Latin ') are Hexapoda, hexapod invertebrates of the class (biology), class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (Insect morphology#Head, head, Thorax (insect anatomy), thorax and abdomen (insect anatomy), abdomen), three pairs of jointed Arthropod leg, legs, compound eyes, and a pair of antenna (biology), antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a insect brain, brain and a ventral nerve cord. Most insects reproduce Oviparous, by laying eggs. Insects Respiratory system of insects, breathe air through a system of Spiracle (arthropods), paired openings along their sides, connected to Trachea#Invertebrates, small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in ves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hymenoptera Of North America
Hymenoptera is a large order (biology), order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are Parasitoid wasp, parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they reach adulthood. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek wikt:πτερόν, πτερόν (''pteron'') for wing. The Ancient Greek wikt:ὑμήν, ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings ...
