Blaberus craniifer
Death's Head Cockroach, Death's-head Cockroach
Blaberus craniifer is a large cockroach species distinguished by the distinctive jack-o'-lantern marking on its pronotum. It exhibits complex sexual behavior including male-produced substrate vibrations and sex pheromones for long-distance female attraction, followed by stereotyped courtship rituals and post-copulatory mate guarding. Unlike the closely related Periplaneta americana, this species shows reduced wind-mediated escape responses and prefers digging behaviors when disturbed. It serves as a host for specific gregarine and nematode parasites that occupy different gut regions without significantly affecting host growth, indicating long co-evolutionary adaptation. The species is valued in entomological collections and hobbyist rearing due to its striking appearance and minimal care requirements.
Chimarocephala pacifica pacifica
A subspecies of band-winged grasshopper in the family Acrididae, known for its complex acoustic and visual communication behaviors. Males produce sounds by rubbing the inner surface of the hind femora against the tegmina. Sexual behavior is mediated through cyclic female receptivity phases, with males employing stridulations, vibrations, and visual signals to communicate with both sexes.
Deuterosminthurus bicinctus
Deuterosminthurus bicinctus is a springtail species in the family Bourletiellidae, first described by Koch in 1840. It is notable for its elaborate courtship and mating rituals involving spermatophore transfer, which have been studied in detail. Males perform a complex sequence of behaviors including a rhythmic head-to-head 'dance' to direct females to deposited spermatophores. The species has been recorded across Europe, the Mediterranean region, Macaronesia, and Australia.
