• Large particles in the main-belt region seem to dominate the dust band emission.
• Dust band features do not persist into the inner Solar System but have a natural inner edge produced by the effect of the near 2 AU secular resonances.
• It may be difficult to distinguish between asteroidal and cometary particles in the inner Solar System on dynamical grounds alone.
• The 'ten degree band' emission does not correlate with Eos family members, but is produced at the inner edge of the inclination distribution.
