DESCRIPTION:The first Euclid Quick Data Release contains millions of galax
 ies with excellent optical and near-infrared (IR) coverage. To complement 
 this data set\, we investigate the average far-IR properties of Euclid-sel
 ected main sequence galaxies using existing Herschel and SCUBA-2 data.  We
  bin the Euclid catalogue by stellar mass and photometric redshift and per
 form a stacking analysis that takes into account galaxy clustering and bin
 -to-bin correlations. We detect stacked far-IR flux across a significant f
 raction of the bins and derive mean dust temperatures\, dust masses\, and 
 star-formation rates (SFRs). We find SFRs that are similar to the optical/
 near-IR estimates\, dust temperatures that seem independent of stellar mas
 s\, and dust-to-stellar mass ratios that decrease from z=1 to the present 
 day. Average dust temperatures seem to decrease with time in a remarkably 
 simple way\, from about 35K at z=2 to 25K at z=0. The interpretation and i
 mplications of these results will be discussed.\n
