AbstractThe larval stages of Agabus elongatus (Gyllenhal, 1826) and A. wasastjernae (Sahlberg, 1824) are described from material from northern Sweden. Descriptions are given of all three larval instars based on reared specimens. Information is given on the natural history of the two species and characters are presented for the separation of these larvae from other described larvae of European Agabus.

AbstractThe morphotogy of the second and third larval instars of Hygrotus decoratus (Gyllenhal, 1810) is described from specimens from the Netherlands. The descriptions are based on specimens taken together with adults. Some information is given on the natural history of the species, and characters for separation of the Dutch Hygrotus larvae are presented.

AbstractThe larval morphology of Agabus striolatus (Gyllenhal, 1808) is described from specimens from the Netherlands and Sweden. Descriptions are given of all three larval instars based on specimens taken together with adults. Information is given on the natural history of the species and characters are presented for the separation of this larva from other described larvae of European Agabus.

The leaf-beetle genus Platypria Guérin-Méneville, 1840 comprises two subgenera and 34 species (Chrysomelidae: Cassidinae: Hispini). Host plants are documented for eight species and indicate mostly perennial species of Fabaceae and Rhamnaceae. Larvae and pupae have been documented for two Platypria species. This paper presents novel natural history data, based on a field study of populations of Platypria (Platypria) hystrix (Fabricius, 1798) on Erythrina stricta Roxb. and Pueraria phaseoloides (Roxb.) Benth. in Kerala, south India and on Erythrina variegata L., Pueraria montana var. lobata (Willd.) Maes. & S. Almeida and Mucuna pruriens (L) DC in Assam, northeast India. Three new Fabaceae hosts are reported for P. (P.) hystrix. Brief notes and new host records, based on field observations, are also provided for the other three species of Platypria in India – P. (P.) chiroptera Gestro, 1899, P. (P.) echidna Guérin-Méneville, 1840 and P. (P.) erinaceus (Fabricius, 1801). Platypria females slit the leaf to lay a single egg which is covered with secretions that harden as an ootheca, the egg covering in Cassidinaes. l. There are five larval stages, each with the typical ‘hispine’ mining form and behaviour – a flattened cream-coloured body, chitinised head capsule and claws, and feeding on mesophyll and leaving irregular blotch mines on the host leaves. Pupation occurs in an independent pupal mine and lasts about a week. These observations suggest new potential phylogenetic character hypotheses that can stimulate better data collection on leaf-mining Cassidinae and help resolve evolutionary patterns amongst these basal mining genera.

Abstract The natural history of our moral stance told here in this commentary reveals the close nexus of morality and basic social-cognitive capacities. Big mysteries about morality thus transform into smaller and more manageable ones. Here, I raise questions regarding the conceptual, ontogenetic, and evolutionary relations of the moral stance to the intentional and group stances and to shared intentionality.
