Update on O. lignaria nests

I haven't seen any blue orchard bees in a couple of weeks, but the berry bees have started using empty tunnels in the one remaining orchard bee Binderboard in the shelter.  There are still 9 tunnels with O. lignaria mud plugs, but in addition there are 4 plugs of chewed leaf material typical of O. aglaia.  At least 4 of the tunnels have bee abdomens visible near the entrance.  I think they are all O. aglaia, but can't tell for sure.

Rosie tells me that there were a few O. lignaria active around her house last week.  The orchard bees there were released quite late, so I suppose it's not too surprising that they are still active.
