We present submillimeter statistical detections of galaxies discovered in the 5'x5' Spitzer Early Release Observations (to ∼4-15 µJy 5 σ at 3.6-8 µm, 170 µJy at 24 µm) through a stacking analysis of our reanalyzed SCUBA 8 mJy survey maps and a Spitzer identification of a new submillimeter point source in the 8 mJy survey region. For sources detected at 5.8 or 8 µm (154 and 111 sources, respectively), we detect positive skews in the submillimeter flux distributions at 99.2%-99.8% confidence using Kolmogorov-Smirnov tests, at both 850 and 450 µm. We also marginally detect the Spitzer 24 µm galaxies at 850 µm at 97% confidence and place limits on the mean submillimeter fluxes of the 3.6 and 4.5 µm sources. Integrating the submillimeter fluxes of the Spitzer populations, we find the 5.8 µm galaxies contribute 0.12±0.05 nW/m2/sr to the 850 µm background and 2.4±0.7 nW/m2/sr to the 450 µm background; similar contributions are made by the 8 µm-selected sample. We infer that the populations dominating the 5.8 and 8 µm extragalactic background light also contribute around a quarter of the 850 µm background and the majority of the 450 µm background.
