Euryopis californica is a species of cobweb spider in the family Theridiidae. It is found in the United States and Mexico. [1] [2] [3] [4] The species is a known predator of Veromessor pergandei ants. [5]
Theridiidae, also known as the tangle-web spiders, cobweb spiders and comb-footed spiders, is a large family of araneomorph spiders first described by Carl Jakob Sundevall in 1833. This diverse, globally distributed family includes over 3,000 species in 124 genera, and is the most common arthropod found in human dwellings throughout the world.
The triangulate cobweb spider is a common spider in the genus Steatoda. It is well known for the triangle-shaped pattern on the dorsal side of its abdomen.
Anatea formicaria is an ant-mimicking spider. It is only known from the rain forest of New Caledonia. Before 1967, it was considered to belong to the family Clubionidae. It was placed there based on the ant-like outward modifications and male genitalia, which superficially resemble those of the genus Micaria. In fact it is closely related to the genera Euryopis and possibly Achaearanea.
Myrmecophagy is a feeding behavior defined by the consumption of termites or ants, particularly as pertaining to those animal species whose diets are largely or exclusively composed of said insect types. Literally, myrmecophagy means "ant-eating" rather than "termite eating". The two habits often overlap, as both of these eusocial insect types often live in large, densely populated nests requiring similar adaptations in the animal species that exploit them.
Dasymutilla is a wasp genus belonging to the family Mutillidae. Their larvae are external parasites to various types of ground-nesting Hymenoptera. Members of this genus are highly variable in sting intensity, ranging from a 1 (D. thetis) to a 3 in the Schmidt sting pain index.
Spiders are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. As of November 2023, 51,673 spider species in 136 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900.
Veromessor pergandei is a species of harvester ant native to the Southwestern United States, especially the deserts of southeastern California. It has also been identified in the Baja California peninsula of Mexico. It was first described by Gustav Mayr, who named it Aphaenogaster pergandei. It can also be referred to as a black harvester ant or desert harvester ant, although these common names have also been applied to other species.
Euryopis is a genus of comb-footed spiders that was first described by Anton Menge in 1868.
