Fig. 3 in A modern type of ant-like stone beetle larva preserved in 99-million-year-old Kachin amber (Coleoptera: Staphylinidae, Scydmaeninae)

Fig. 3 – Schematic restorations of ant-like stone beetles. A – The new fossil (based on Fig. 1); not to scale. B – Stage 2 larva of the extant species Stenomastigus longicornis (based on Jałoszyński & Kilian 2016 figs 1–4 p. 153); not to scale; note the similarities to the fossil larva. C–G – Restorations of different fossils, all to the same scale for size comparison. C–E – Fossils of adult ant-like stone beetles. C) Clidicostigus arachnipes (based on Jałoszyński et al. 2017 fig. 3A p. 114). D) Cascomastigus monstrabilis (based on Yin et al. 2017b fig. 1a p. 2). E) Cascomastigus minor (based on Yin et al. 2018b fig. 2A; width of body estimated based on the other species). F) The new fossil (same as A), but to scale. G) Estimated size of a possible stage 3 larva following the stage 2 larva which the new fossil presumably represents (by simply resizing the latter to 200%).
