Using light trapping from&nbsp;dawn to sunset over a 1-year period in French Guiana, we investigated&nbsp;these variations within and between two families of moths (Sphingidae&nbsp;and Saturniidae). Our results revealed contrasting patterns in flight activity&nbsp;at night between Sphingidae and Saturniidae. Sphingidae reached their&nbsp;peak in species richness and abundance between 7:00 and 8:00 p.m.,&nbsp;followed by a decrease around 11:00 p.m. to midnight, whereas&nbsp;Saturniidae were continuously present throughout the night, with a peak&nbsp;around midnight. In addition, we found changes in diel activity among&nbsp;some of the most common genera in each family, highlighting distinct&nbsp;behavioral, physiological, and functional traits among taxa. Given differences&nbsp;in flight activity at different taxonomic levels, it is strongly recommended&nbsp;to monitor by light trapping throughout the night to effectively&nbsp;sample saturniid and sphingid assemblages, even though the activity of&nbsp;Sphingidae sharply declines after midnight. These results improve the&nbsp;general natural history information of tropical moths and reinforce the&nbsp;need of further research on the ecological and taxonomic consequences&nbsp;of differences in diel activity.</p>

The existence of two and three cryptic species respectively within the X. loelia and X. neoptolemus complexes is revealed following consideration of both adult habitus and genital morphology, and the results of a phylogenetic analysis of partial COI sequences—DNA barcodes—for 38 specimens. The taxonomic status of the available names is discussed and to clarify and stabilize the confused nomenclature of this group, a neotype for Sphinx neoptolemus Cramer, 1780, and lectotypes for Choerocampa loelia Druce, 1878 and Chaerocampa trilineata Walker, [1865], are designated. We describe three new species: X. lolita n. sp. Vaglia and Haxaire; X. balcazari n. sp. Haxaire and Vaglia; and X. cthulhu n. sp. Haxaire and Vaglia. The first is endemic to southeastern Brazil and closely allied to X. loelia; the second two are relatives of X. neoptolemus, of which the first is known only from Guerrero and Michoacán states in Mexico while the second is widely distributed in lowland forests of Central America.10acentral america10acoi10adna barcodes10anew species10asouth america1 aVaglia, T.1 aHaxaire, J.1 aKitching, I.J.1 aMeusnier, I.1 aRougerie, R.  uhttps://insectafgseag.myspecies.info/fr/node/497
