Neococytius is a in the Sphingidae, containing only the Neococytius cluentius, commonly known as the Cluentius sphinx. This large sphinx moth has an exceptionally long , historically measured at approximately 25 cm, which has been discussed in relation to pollination of night-blooming cacti. The genus was erected by Ronald W. Hodges in 1971, with the sole species originally described by Pieter Cramer in 1775.

Piperaceae - larval food plant
Ipomoea batatas - larval food plantsweet potato

Life Cycle

At least three per year in tropical regions.

Behavior

are . The has been discussed as a potential of night-blooming cacti due to its exceptionally long .

Ecological Role

Potential of night-blooming cacti; larval herbivore on various plant .

Human Relevance

Larvae feed on sweet potato (Ipomoea batatas), suggesting minor agricultural relevance. Historical scientific interest due to length and potential cactus pollination mutualism.

Similar Taxa

CocytiusNeococytius was historically treated as part of Cocytius (as Cocytius cluentius) but was separated as a distinct by Hodges in 1971 based on morphological differences.

Misconceptions

The name "Cocytius cruentus" has been used erroneously in literature discussing cactus pollination; the correct specific epithet is cluentius.

More Details

Proboscis length

Otto Porsch in 1939 reported the length as 25 cm, one of the longest recorded for any , in the context of potential cactus pollination.

Taxonomic history

The has been known under multiple combinations: originally Sphinx cluentius Cramer, 1775; later Cocytius cluentius; and currently Neococytius cluentius since Hodges' generic revision in 1971.
