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>
