In the northeastern region from Brazil was registered the growth with insufficiently known areas, been some considered extremely important for biodiversity conservation from Caatinga biome, amongst them Chapada do Araripe. The lack of knowledge for many groups, including the Lepidoptera taxon, has less representation in scientific collections in this region. The sphingids (Lepidoptera: Sphingidae) are widespread moths, been acknowledgments as biological indicators, pollinators vegetal species in tropical regions, foods for other animals, and host for ectoparasites. Thus, the research aimed to collect data of sphingids fauna attracted for artificial source light, its ectoparasites, and analyze the composition of vegetal species used as floral resources by assemblage sphingids in "brejo de encosta" in municipality Santana do Cariri, CE. Therefore, was performed collects of moths belong to family Sphingidae between 1730h until 0530h in three days of new moon per month for two years (August/2016 until July/2018) in Environment Protect Area Chapada do Araripe in municipality Santana do Cariri, CE. The moths were attracted to the luminal trap used mixed lamp 250watts, hand captured and euthanized with ammonia in metatórax. A total of 3690 specimens were sampled belong to 37 species and 18 genera. The species Erinnyis ello ello, Xylophanes tersa, and Hyles euphorbiarum were more abundant, comprises together 74% of all specimens collected. The nine species moth was registered for the first time in Ceará state. The specimens host were investigated for mites ectoparasites and were identified as the presence of the Erythraeidae and Otopheidomenidae family. There were observed a total of 18 species of sphingids host and 122 individuals infected with mites in its body with a prevalence of 3.3%. There were a first registered of Caeculisoma selmae parasitizing sphingids and Prasadiseius donahuei to Brazil, parasitizing more than 14 species. For the first time, an individual was observed to be infested by two species of otopheidomenids. To find out what resources are used by these moths, proboscis was extracted from all collected specimens, being separated by species, sex, and month. For the analysis of pollens attached to them, pollen slides were prepared using the acetolysis method. There was a pollen record in 29 species, 91 pollen types belonging to 36 families were identified, and with new records for Brazil of 11 of them and 63 pollen types. The predominance of pollen types for the two years was Fabaceae (20%). The largest records of pollen types adhered to proboscis were Erinnyis ello ello, Xylophanes tersa and Agrius cingulata with 65, 31, and 28, respectively. A total of 15% of species and 41% of angiosperm families registered for the region were visited by sphinxes. For Brazil, there was an expansion of 18% of the plant families and 28% of the pollen types used by the sphingids as a floral resource. For the state of Ceará, all data are new records. The present research contributed with basic knowledge about the composi...
