FIGURE 2 in Another strange holometabolan larva from Kachin amber-the enigma of the beak larva (Neuropteriformia)

FIGURE 2. Comparison of drawings of the different beak larvae and other larvae to illustrate possible ontogenetic changes. A,?Partisaniferus edjarzembowskii sp. nov., beak larva 3, SNHM-6013; scale bar on the lower right. B–D, All known beak larvae at the same scale; note that the larva in B has a much larger body size than those in C and D; scale bar between B and D applies to B–D. B, Possible second specimen of?Partisaniferus edjarzembowskii sp. nov., beak larva 2, based on Haug et al. (2022b). C,?Partisaniferus edjarzembowskii sp. nov., beak larva 3, based on this study. D, Partisaniferus atrickmuelleri, beak larva 1, based on Haug et al. (2020e). E. Enlarged version of D; scale bar on the lower right. F and G, Comparison of first and last larval stage of a representative of Nevrorthidae at the same scale; scale bar under G applies to F and G. F, Last larval stage of Nevrorthus sp. based on Gepp (1984). G. First larval stage based on Haug et al. (2019b). H and I, Comparison of first and last larval stage of a representative of Psychopsidae (Psychopsis elegans) at the same scale based on Tillyard (1918); size provided by magnification factor, hence no scale bar provided. H, Last larval stage. I, First larval stage.
