    We introduce the 4-metre Multi-Object Spectroscopic Telescope (4MOST), a new high-multiplex, wide-field spectroscopic survey facility under development for the four-metre-class Visible and Infrared Survey Telescope for Astronomy (VISTA) at Paranal. Its key specifications are: a large field of view (FoV) of 4.2 square degrees and a high multiplex capability, with 1624 fibres feeding two low-resolution spectrographs (R=λ/Δλ∌6500R = \lambda/\Delta\lambda \sim 6500), and 812 fibres transferring light to the high-resolution spectrograph (R∌20 000R \sim 20\,000). After a description of the instrument and its expected performance, a short overview is given of its operational scheme and planned 4MOST Consortium science; these aspects are covered in more detail in other articles in this edition of The Messenger. Finally, the processes, schedules, and policies concerning the selection of ESO Community Surveys are presented, commencing with a singular opportunity to submit Letters of Intent for Public Surveys during the first five years of 4MOST operations

    Eggs, larvae, and pupae of the blow fly Calliphora vicina reared normally at 24°C were kept for 24 h at an ambient temperature of 3.0±0.14°C during growth and development. This was to stimlate the chilling of insects before their collection from cadavers in a morgue at 3°C in forensic entomology cases. Such treatment of any stage induced a 24 h delay in adult emergence because the insects did not appear to develop while chilled. No mortality occurred in any stage, including eggs and 1st instar larvae, during chilling. This information is important for, and should improve the accuracy of forensic investigations.Key words: Forensic entomology; maggot; British Columbia; refrigeration; developmen
