# Anopheles (Cellia) fluviatilis species complex
Little detailed information is available on the bionomics, ecology and distribution of An. fluviatilis outside of India and Iran.
A study conducted in Orissa State of India showed that members of this Complex are essentially absent in deforested areas, but Anopheles fluviatilis S is the predominant species in forested areas (98% species S; 2% species T). Larvae of An. fluviatilis are generally associated with slow-flowing streams or river margins, in direct or diffuse sunlight. They have also been reported from rice fields, often in low numbers, possibly washed into the fields from the irrigation channels where they tend to be found in higher densities.
# Resting and feeding preferences
Anopheles fluviatilis S is the most anthropophilic and endophilic species of the Complex. An. fluviatilis T and U are primarily zoophilic, exophagic and exophilic. Biting activity begins around 19:00 and peaks between 20:00 and 21:00, but may also occur throughout the night until dawn without an apparent peak.
# Vectorial capacity
Anopheles fluviatilis S is regarded as a highly efficient malaria vector in hilly regions of India. An. fluviatilis T and U are considered to be poor or non-vectors in India. However, in Pakistan, Nepal and Iran, species T has been recorded as an important malaria vector in general, or a localised vector for maintaining malaria in mountainous and hilly regions.
