  We present Spitzer 24micron imaging of 1.5 < z < 2.5 Distant Red Galaxies
(DRGs) in the 10arcmin by 10arcmin Extended Hubble Deep Field South of the
Multiwavelength Survey by Yale-Chile. We detect 65% of the DRGs with K_AB <
23.2 mag at S_24micron > 40uJy, and conclude that the bulk of the DRG
population are dusty active galaxies. A mid-infrared (MIR) color analysis with
IRAC data suggests that the MIR fluxes are not dominated by buried AGN, and we
interpret the high detection rate as evidence for a high average star formation
rate of <SFR> = 130+/-30 M/yr. From this, we infer that DRGs are important
contributors to the cosmic star formation rate density at z ~ 2, at a level of
\~0.02 M/yr/Mpc^3 to our completeness limit of K_AB = 22.9 mag
