Definition
Cacama crepitans is a species of cicada belonging to the family Cicadidae. It is classified within the order Hemiptera and the genus Cacama, which comprises several North American cicada species.
Overview
The taxonomic hierarchy of Cacama crepitans is as follows:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Hemiptera
- Suborder: Auchenorrhyncha
- Family: Cicadidae
- Genus: Cacama
- Species: C. crepitans
The species was formally described in the early 20th century, although the exact author and year of description are not consistently cited across sources. Members of the genus Cacama are primarily associated with arid and semi‑arid habitats in the southwestern United States and northern Mexico, where they are known for their distinctive acoustic signals.
Etymology / Origin
The generic name Cacama is derived from a Latinized form that may allude to a perceived “noisy” or “clamorous” character, a common theme in cicada nomenclature, though the precise etymological root is not definitively documented. The specific epithet crepitans comes from the Latin verb crepitāre, meaning “to crackle” or “to make a rattling sound.” This likely references the characteristic call produced by the adult male.
Characteristics
- Morphology: As with other Cacama species, adults of C. crepitans possess a robust body, transparent wings with prominent venation, and large compound eyes. Specific coloration patterns for this species are not well‑recorded in the literature; however, congeners typically exhibit earthy tones ranging from grayish‑brown to olive.
- Acoustic behavior: The species name suggests a “crackling” song; males are known to produce a series of rapid, rattling pulses that differentiate them from other cicadas in the region. Detailed sonographic analyses of the call are lacking.
- Life cycle: Like all cicadas, C. crepitans undergoes incomplete metamorphosis, with nymphal stages spent underground feeding on plant root xylem. The duration of the nymphal period for this species has not been conclusively determined, but related Cacama species exhibit multi‑year subterranean development before emerging as adults in the summer months.
- Habitat: Recorded habitats include scrubland and open woodland where host plants are available. Precise host plant associations for C. crepitans remain undocumented.

Accurate information is not confirmed for several specific aspects of Cacama crepitans, including detailed distribution, precise morphological measurements, and nymphal development time. Further taxonomic and ecological research is required to fully characterize this species.
