I can only guess what happened, but the eggs were there last night (night of the 12th) and were still there the morning of the 13th.  So I went down around lights out tonight on 11-13 to pull the tile..and the eggs are gone.  No larvae anywhere, which would suggest the hatch happened much earlier in the day.  I’m starting to wonder – are my Lightning Maroons “day hatching”?  It would seem to make sense and explain some of the “weird” hatches I’ve had and missed in the past.
