“…Concerning the weight of the pupae, it should be noted that the variation of twice the value between the lightest and the heaviest pupae (250–511 mg) obtained in this study is also reported in other studies that evaluate the development of other Noctuinae on an artificial diet (Specht et al 2020, 2021). The longevity of females in this study (Table 3) at 25°C (15.85 days) was similar to that observed for the same species maintained at 22°C by Foerster and Mello (1996) (17.7 days).…”

“…However, our database lacks records of A. ignicans from the whole Amazon region, Caatinga, trans‐Andean Colombia and southern Panama. The scarcity of records in these locations (or similar areas) is also observed in other Agrotini (Specht et al 2021), thus corroborating a distribution pattern similar to this group of species. Its relationship with xeric and/or grass‐dominated ecosystems is well known in the literature, although it is emphasised for species with a Nearctic distribution (Crabo & Kirst 2023; Lafontaine 2004).…”

“…The general morphology, behaviour of laying eggs in masses and egg colour of A. ignicans are very similar to A. infecta (Teston et al 2001), A. mahalpa (Specht et al 2008) and Praina temperata (Schaus, 1894) (Specht et al 2021). However, the egg of A. ignicans has a reduced number of ribs compared to the egg of A. infecta (Peterson 1964).…”

“…One of the main characters supporting Austrandesiina is the smooth texture of the integument, classified as ‘microgranular skin’ (Lafontaine 2004). Anicla ignicans larvae have a smooth integument like P. saucia (Venâncio et al 2021) and P. temperata (Specht et al 2021). However, the morphology of the granules of the integument can change depending on the species and the instar it is found; for example, in the first instar, A. ignicans have granules that are wide, conical and sparser compared to those of the sixth instar, which are more tapered and elongated, like blunt spines, and less spaced.…”

“…Despite the difficulties in species identification, the size of the larvae and pupae can be useful for separating A. ignicans from A. infecta and A. mahalpa , as already noted (Specht et al 2008; Teston et al 2001). However, for species with a wide distribution, such as A. ignicans and A. infecta , care must be taken when considering only this character, as variations in size may be related to biotic, abiotic and geographical factors, and variation can be present even in specimens from the same population (Specht et al 2021).…”

The subgenus Anicla, commonly known as green cutworms, harbours some of the owlet moths (Lepidoptera: Noctuinae), whose larvae are notable for their economic importance. Knowledge of the immature stages for this group is available for three of the nine described species. Anicla infecta Ochsenheimer, 1816 is widely distributed in the Americas and is especially abundant in agricultural ecosystems. However, in the Neotropics, its economic damage can be confused with sympatric species, including Anicla ignicans (Guenée, 1852), whose distributions overlap in most parts of the American continent. In this sense, here, the identity of A. ignicans is investigated through its geographical distribution, based on molecular and morphological data. Additionally, the morphological and behavioural traits of immature stages were described in detail, information about its geographical distribution and larval host plants was gathered, and the species' biological parameters from larvae reared on an artificial diet were determined. Anicla ignicans is distributed throughout the Neotropical region, preferably in areas with xeric and/or grass‐dominated ecosystems. The eggs present valuable characters to distinguish A. ignicans from other owlet moth species, such as the reduced number of ribs, the way the micropyle openings are arranged and the shape of the aeropyles. However, the larvae show very similar chromatic polymorphisms to other Anicla species. Although A. ignicans prefer to feed on grasses, it was observed that more than 85% of the larvae that were fed with a modified bean‐based Greene diet survived. Additionally, the percentage of time for each phase of development obtained here is very similar for the different species of Anicla, regardless of the temperature or feeding of the larvae.
