Why is this code drawing sprites in reverse order?

I've got the following piece of code:

spriteBatch.Begin(SpriteSortMode.FrontToBack, BlendState.AlphaBlend, null, null, null, null, cam.TransformMatrix);
spriteBatch.Draw(_comicBackground, workspace, Color.AliceBlue);
foreach (LayoutField lf in comicStrip.LayoutFields)
{
    spriteBatch.Draw(_layoutFieldBackground, new Rectangle(lf.PosX, lf.PosY, lf.Width, lf.Height), Color.White);
}
spriteBatch.End();

but regardless of SpriteSortMode (FrontToBack | BackToFront) background is always being displayed on top of the results of foreach loop, covering my layout in the result.

It's not a show-stopper as I can draw my sprites in reverse order but I'd rather keep them in the order in which they should be drawn on the screen.

The FrontToBack and BackToFront sort modes require you to specify a sprite depth value in your Draw() calls; see the layerDepth parameter here. If you want to draw sprites in the order that you make the Draw() calls, use SpriteSortMode.Deferred or SpriteSortMode.Immediate.
