Ablautus trifarius is a small robber fly in the family Asilidae, first described by Loew in 1866. Adults measure approximately 6–7 millimeters and are sand-colored, making them difficult to detect in their natural environment. The species is predatory in both larval and adult stages, preying on insects smaller than themselves such as leafhoppers. Males exhibit distinctive courtship behavior involving aerial displays, leg-waving, and rocking movements.
Alopecosa aculeata
Spinyrib Wolf Spider
Alopecosa aculeata is a species of wolf spider in the family Lycosidae, found across a broad geographic range spanning North America, Europe, and Asia. Taxonomic study has revealed that specimens historically identified as this species actually represent two distinct species, with A. aculeata and A. taeniata now recognized as separate based on morphological, behavioral, and ecological differences. The species exhibits distinct courtship behavior and habitat preferences that differ from its close relatives.
Anaxipha
Brown Sword-tail Crickets
Anaxipha is a genus of small swordtail crickets distributed across tropical and subtropical regions worldwide, including the Americas, Africa, Asia, Australia, and western Pacific islands. Members are known as "brown sword-tail crickets" and are characterized by their acoustic communication systems, which in several studied species include both calling songs and previously undocumented courtship songs with substrate-borne vibrational signals (drumming). Some species occupy agricultural habitats such as rice fields, where they function as generalist predators.

Males of some Empis species are notable for possessing modified hind legs with enlarged structures used in courtship displays.
Empyreuma
spotted oleander caterpillar moth
Empyreuma is a genus of tiger moths in the family Erebidae, containing three species. The genus name derives from the Greek ἐμπύρευμα, meaning "a live coal covered with ashes." Adults exhibit striking aposematic coloration with orange and black patterns that mimic stinging wasps. Larvae feed exclusively on oleander (Nerium oleander), a toxic plant containing cardiac glycosides that the caterpillars sequester for their own defense. The genus is notable for its acoustic courtship behavior, with males producing sounds detected by female tympanic organs.
Habronattus calcaratus calcaratus
Habronattus calcaratus calcaratus is a subspecies of jumping spider in the family Salticidae. It belongs to the genus Habronattus, a large group of small spiders with approximately 100 species, most occurring in North America. The specific epithet 'calcaratus' refers to a calcar or spur, likely referencing a distinctive morphological feature. As a member of the Habronattus genus, it likely shares the characteristic elaborate courtship behaviors involving visual and acoustic signals that have been documented in related species.
Habronattus dossenus
A small jumping spider in the genus Habronattus, native to Mexico and the southwestern United States. Males are renowned for producing complex multimodal courtship displays combining visual signals with seismic (vibratory) signals generated by dorsoventral abdominal vibrations against the substrate. Signal efficacy varies dramatically by substrate type, with leaf litter providing the most favorable transmission environment compared to rocks or sand.
Hentzia
Long-jawed Jumping Spiders
Hentzia is a genus of jumping spiders (Salticidae) in the subfamily Dendryphantinae, established by G. Marx in 1883 and named after arachnologist Nicholas Marcellus Hentz. The genus contains approximately 22 recognized species distributed primarily in the Caribbean region, with Cuba hosting the greatest diversity (seven species). North American species include the widespread H. palmarum and H. mitrata, along with western outlier species H. poenitens and H. fimbriata. Males exhibit elaborate courtship displays involving leg spreading, abdominal cocking, and zigzag approaches toward females.
Hentzia palmarum
common hentz jumper, common Hentz jumping spider
Hentzia palmarum is a small jumping spider in the family Salticidae, commonly known as the common hentz jumper. Males possess conspicuously enlarged and darkened front legs that function in visual signaling during courtship and male-male agonistic interactions. The species occurs across North America and has been introduced to Bermuda, the Bahamas, and Cuba.
Heteropogon divisus
Heteropogon divisus is a species of robber fly in the family Asilidae, subfamily Brachyrhopalinae. The genus Heteropogon comprises small to medium-sized robber flies with distinctive courtship behaviors. Adults are predatory, capturing other insects in flight and feeding on them using piercing-sucking mouthparts. The species was described by Coquillett in 1902.
Heteropogon macerinus
Heteropogon macerinus is a small robber fly in the family Asilidae, measuring approximately 10 mm in length. The species exhibits distinctive courtship behavior in which males hover before females and stroke their eyeballs with ornamented front tarsi. Adults are predatory, capturing other insects in flight and returning to perches to feed. The species frequents forest edges where it perches conspicuously on twig tips at eye level.
Heteropogon maculinervis
Heteropogon maculinervis is a species of robber fly in the family Asilidae, described by James in 1937. The genus Heteropogon comprises small to medium-sized predatory flies known for their distinctive courtship behaviors. As with other asilids, adults are aerial predators that capture other insects in flight. The species name 'maculinervis' refers to spotted or marked wing veins.

Pyrota is a genus of blister beetles in the family Meloidae, comprising at least 30 described species. The genus is characterized by complex and highly distinctive courtship behavior involving prolonged physical contact between sexes. Males alternate between mounting above females for dorsal acts (palpation, dorsal antennation, rocking) and positioning behind them for posterior acts (leg grasp, palpal insertion beneath elytra, lifting female body, posterior antennation, abdominal curvature and stroke, genital hold). Adults exhibit little aggressive behavior and copulate in a linear position for extended periods with abdominal pumping by the male. Some species show extreme size dimorphism between mating individuals.
Rhamphomyia vittata
Rhamphomyia vittata is a species of dance fly in the family Empididae, described by Loew in 1862. It belongs to the large genus Rhamphomyia, which contains many species known for their distinctive courtship behaviors involving nuptial gifts. Like other members of this genus, males likely present food gifts to females during mating. The species is part of the subgenus Pararhamphomyia.
Scaptodrosophila
Scaptodrosophila is a large genus of fruit flies in the family Drosophilidae, comprising over 250 described species distributed across multiple continents. The genus exhibits considerable diversity in Australia, where multiple species groups have been studied for their courtship behaviors and host-plant associations. Some species are specialized flower-breeders, with documented cases of host-race formation on Hibiscus species. The genus has been subject to taxonomic revision in multiple regions including India and Australia.
Schizocosa
Brush-legged Spiders
Schizocosa is a genus of wolf spiders (Lycosidae) comprising 56 species distributed across North and South America, Africa, and East and Southeast Asia. Members are medium to large spiders (5–15 mm, occasionally to 28 mm) with strong legs, keen eyesight, and distinctive carapace morphology. The genus is notable for elaborate male courtship behaviors involving vibratory and acoustic signals, with some species exhibiting prominent leg ornamentation. Several species have been extensively studied for sexual selection, reproductive isolation, and behavioral ecology.
Sminthurididae
Sminthurididae is a family of globular springtails (Collembola: Symphypleona) distinguished by extreme sexual dimorphism, particularly in antennae structure and body size. Males possess clasper-shaped modified antennae used in courtship displays, while females retain unmodified antennae; males are also markedly smaller than females. The family comprises approximately 155 species across 12 extant genera, with notable diversity in the Neotropical region. Diagnostic morphological features include spherical short ventral tube sacs, presence of all abdominal bothriotricha (A–E), and absence of subanal appendage in females.
Tegrodera
iron cross blister beetles, iron cross soldier beetles, soldier blister beetles
Tegrodera is a North American genus of large, colorful blister beetles in the family Meloidae, comprising three allopatric species. The genus is confined to arid and semi-arid regions of southwestern North America, with each species occupying distinct geographic ranges separated by major desert barriers. Adults are conspicuous and often form immense feeding and mating aggregations. All species contain cantharidin, a defensive compound toxic to mammals. The genus is notable for unique male courtship behavior involving antennal grasping and stimulation.
Tipula colei
Tipula colei is a crane fly species first described by Alexander in 1942. It belongs to the subgenus Triplicitipula within the large genus Tipula. The species has been documented from residential areas in Baton Rouge, Louisiana, and is distributed across parts of the eastern United States and Mexico. Detailed behavioral studies reveal complex male genital courtship functions involving rhythmic stimulation of females during extended copulation periods lasting approximately three hours.
