We present NIR and MIR observations of eight embedded young stellar groupsaround Herbig Ae/Be stars (HAEBEs) using archived Spitzer IRAC data and 2MASSdata. These young stellar groups are nearby ($\leq$ 1 kpc) and still embeddedwithin their molecular clouds. In order to identify the young stellar objectsin our sample, we use the color-color diagram of J - [3.6] vs. Ks - [4.5]. TheSpitzer images of our sample show that the groups around HAEBEs, spectral typesearlier than B8, are usually associated with bright infrared nebulosity. Withinthis, there are normally 10 - 50 young stars distributed close to the HAEBEs($<$ 1 pc). Not only are there young stars around the HAEBEs, there are alsoyoung stellar populations throughout the whole cloud, some are distributed andsome are clumped. The groups around the HAEBEs are sub-structures of the largeyoung population within the molecular cloud. The sizes of groups are alsocomparable with those sub-structures seen in massive clusters. Young stars ingroups around HAEBEs have generally larger SED slopes compared to thoseoutside, which suggests that the young stars in groups are probably youngerthan the distributed systems. This might imply that there is usually a higherand more continuous star forming rate in groups, that the formation of groupsinitiates later, or that low mass stars in groups form slower than thoseoutside. Finally, there is no obvious trend between the SED slopes and thedistance to the HAEBEs for those young stars within the groups. This suggeststhat the clustering of young stars dominates over the effect of massive starson the low-mass young stars at the scale of our study.
