We study the Large Magellanic Cloud Papillon Nebula (N 159-5), a
conspicuous High Excitation Blob (HEB) lying in the star forming
complex N 159. Using JHK near-infrared photometry obtained at
the ESO VLT with the ISAAC camera, we examine the stellar populations
associated with the Papillon, tracing their history using stellar
evolution models. Two populations are revealed: one composed of young,
massive stars with an age ~3 Myr, and a second consisting of
older lower mass stars of age spreading between 1 and 10 Gyr. We
analyze the properties of those populations and discuss their
significance in the context of N 159. We also estimate that if the
star at the center of the Papillon is single its initial mass is
~50 and it is affected by an extinction AV ~ 7 mag.
