The female produced sex pheromone of Aleochara curtula has been described to consist of a mixture of (Z)-7-henicosene and (Z)-7-tricosene [114]. The same compounds are reported to be used by young males as a kind of camouflage to avoid aggression from older males. Similarly, chemical camouflage by using hydrocarbons plays a role in the relations between the myrme-cophilous staphylinid beetle Zyras cones and the ant Lasius fuliginosus. The host worker ants never attack these beetles which show the same profiles of cuticular hydrocarbons as the ants [115]. 

Specimens of the pollen-feeding staphylinid beetle Eusphalerum minutum were found in cantharidin traps, which indicates that they are canthariphilous [121]. In addition, they contain small amounts of cantharidin 48, which is accompanied by palasonin 49. Palasonin has been previously only known from seeds and fruits of the Indian shrub Butea frondosa (Leguminaceae [122]). 

Pederin (104), the powerful cytotoxin of staphylinid beetles of the genus Paederus, has been the object of renewed interest due to the unexpected discovery of a series of closely related compounds in marine sponges that display antitumor activities. The latter, as well as pederin, were prepared by total synthesis and their biological activities were reported [219,220]. A recent review summarizing present knowledge on this family of compounds has been published [221]. 

The staphylinid beetle Stenus comma secretes the alkaloid stenusine (120) which has water spreading properties and thus allows the insect to move easily over the surface of the water. The absolute stereochemistry of the base has not been established, although the gross structure (120) has been synthesised (H. Schildknecht et al., Angew Chem. Intern.Ed., 1975, 14, 427). Australian mealy bugs Cryptolaemus montrouzieri excrete the dialkyIpiperidine (121), and probably also the trans-isomer as well (W.V. 

The host-specific staphylinid beetle Trichopsenius frosti has a blend of cuticular hydrocarbons that are identical to those of its host, Reticulitermes flavipes (Howard et al., 1978). The beetle grooms workers and rides on the back of female reproductives. This appears to be a case of chemical mimicry of the species-recognition pheromones of the host. 

A total synthesis of ( )-pederamide (36), a key intermediate in a projected synthesis of pederin, a vesicant component of the staphylinid beetle, has been accomplished. ... 

Originally, the Fauna Europaea project aimed at covering all non-marine species of metazoans in Europe. At the time of the first release, it was estimated that a few thousand species entries had still to be added, the largest missing set being a subgroup of the staphylinid beetles. I will briefly outline below some critical steps in the history of the Fauna Europaea project, as a background for a subsequent discussion of the most important lessons we learned from this work.
