Description:
The larvae of Netocia morio (Fabricius, 1781), Netocia oblonga (Gory & Percheron, 1833), Potosia opaca (Fabricius, 1787) and Potosia cuprea brancoi Baraud 1992 are described. Comparison of the morphology of both genera revealed important differences in raster structure, mandibles and frontal setae. The systematic position of both genera based on larval characteristics is discussed. Some aspects of larval biology are discussed.

Description:
Pollinating insects are important and therefore, it is important to be able to assess and monitor changes in their abundance. Consequently, it is essential that the methods used to collect data have some level of precision and are accurate. In the present study, two commonly used methods: colour pan-traps and sweep netting along transects, were compared. A total of 1775 specimens of 120 species of four insect families were caught in twelve clear-cuts in southern Sweden. Overall, Lepturinae (Cerambycidae; 5 species) and Cetoniidae (Scarabaeidae; 2) were trapped in larger numbers by pan-traps and Syrphidae (62) and Apoidea, both social (10) and solitary (41), by sweep netting. The catches of none of the above groups of insects by the two methods were correlated. These results show that the composition of catches of the two methods are very different, which has implications when choosing a method for sampling or monitoring and comparing and analysing published data.
