The fall armyworm Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is one of the most important pests in Brazilian maize fields that causes damage to approximately 57% of the crop (Cruz etal., 1999 S.). However, several biological control agents occur freely in agroecosystems and are known to suppress the S. frugiperda population (Dequech et al., 2004 ; Bortolotto et al., 2014 ). Among the predator insects, hoverflies have been reported to occur in maize fields but are usually associated with aphid infestation (Swaminathanet al., 2015). Thus far, few studies have investigated hoverflies preying on lepidopteran pests, and the spectrum of preys examined is unclear. To our knowledge, this is the first report of Toxomerus dispar larvae (Fabricius, 1794) (Diptera: Syrphidae) preying on S. frugiperda caterpillars (Figure 1).Thirty specimens of hoverfly larvae were collected from 100 plants (in V
