  Using HST WFPC2 images, we have obtained U, B, V, I, and H-alpha photometry
for 76 star clusters in the nuclear star-forming ring of the barred spiral
galaxy NGC 4314. These clusters are likely associated with an inner Inner
Lindblad Resonance, or IILR. The blue colors and H-alpha emission for most of
these clusters imply very young ages of 1-15 Myr. Age estimates based on
several reddening-free parameters indicate that the present epoch of star
formation has lasted at least 30 Myr. By estimating the masses of stars in the
clusters and comparing with the H-alpha luminosity, we conclude that a
significant fraction of ongoing star formation in the nuclear ring of NGC 4314
occurs in clusters. The cluster masses identify these as young open clusters,
not young globular clusters. Further out in the galaxy, just exterior to the
ring of young stars, previous ground-based observations revealed two symmetric
stellar spiral arms which may be associated with an outer Inner Lindblad
Resonance, or OILR. With our HST data, we have revealed part of this structure
and its colors in more detail. The spiral arm colors are consistent with
stellar ages between 40 and 200 Myr. The age difference between the inner ring
of young stars (IILR) and the larger oval-like feature containing the blue arms
(OILR) supports an interpretation of the morphology of the nuclear region of
NGC 4314 that requires a reservoir of gas that becomes more compact over time.
We speculate that as the gas distribution becomes more centrally concentrated,
it interacts with these two resonances. Each resonance triggers star formation,
resulting in two distinct epochs of star formation.
