Insect sounds are predominantly produced by stridulations, where specialised body parts contact repeatedly to induce acoustic pulse trains. We studied the stridulatory organ and sound emissions in Copris lunaris, by focussing separately on females, and on major and minor males. Results highlighted an isometric growth of pars stridens in response to body size, and identified a wing-pygidium locking structure that assists sound emission. Sex-specific acoustic differences of some degree were detected between major males and females, as sounds emitted by majors showed higher frequencies and shorter pulses with elevated impulse rates. This cannot be immediately explained by size differences in the components of stridulatory apparatus. Rather, divergence might be an indicator of some underlying behavioural difference in response to distressing events. In minor males, acoustic properties overlapped with both females and major males, although incomplete stridulations had a lower ratio in minor than major males. This paper provides the very first perspective of the potential role of sex and male polymorphism on sound production. However, future categorisations of sounds coupled to behavioural observations of specific interactions are needed to reveal the function of sex and morph-specific differences.

Immature stages of Scaptodera rhadamistus (Fabricius) are described for the first time along with notes on nidification and biology. The larvae differ from other Scarabaeinae species in the structure of raster on tenth sternum with two irregular bunches of serrations ventrally one on either half. Pupae with pronotum transverse having rounded margins resemble adults, and consist of four lateral, single caudal and single pteronotal support projection. Adult males and females differ in coloration, structure of pronotum, presence of spine like process on mesosternum and, in the structure of male and female genitalia.

Osmoderma eremita (Scopoli, 1763) is a saproxylic scarab beetle protected by the Habitats Directive in the European Union. The present paper is part of a special issue on monitoring of saproxylic beetles protected in Europe and starts with a revision of the current knowledge on systematics, ecology, ethology and conservation of O. eremita and its allied species, followed by experimental tests of different methods for monitoring its populations. Two methods were compared in several localities of central Italy: (1) the widely used pitfall traps into tree cavities and (2) black cross windows traps baited with a specific pheromone produced by male beetles. The first method, often used in northern and central Europe, did not give acceptable results in Italy probably because of the scarcity of veteran trees with large hollows. It could only be used successfully in areas where: 1) tree hollows were abundant, large enough and with sufficient amounts of wood mould for planting pitfall traps and 2) the team is composed of several operators in order to ensure the checking of at least 150 traps every two days during the whole period of mating activities (15 July–25 August). The second method, consisting of hanging 30 black cross window traps during the mating period and checking them every two days, turned out to be better for capturing a significant number of individuals but cannot be used every year because of the possible disturbance on mating activities of the species.
