Our Lilacs Finally Bloomed

Our lilacs seemed to remain in a state of "almost blooming" for over a month before the right combination of soil temperature, length of daylight, and available moisture, got them motivated to bloom.  The lilacs in the sunnier parts of downtown had been blooming since late March.  When ours bloomed, they were visited almost immediately by the usual array of insects: several species of bees and butterflies, the most colorful of which was the Painted Ladies (top two photos).  I haven't identified the one in the bottom photo.  It reminded me of all those little brown birds that I can't tell apart.
