: For my wild population of Mason Bees, I keep 1/4" cardboard tubes, 5/16"
: plastic tubing and 3/16" drinking straws handy for them. They use the
: drinking straws most often.
: This year something strange has happened: I have always saw mud having
: been used to seal the entrance but this year some of the 1/4" tubes are
: sealed with a mucilaginous substance. Does anyone know what this substance
: might be or what insect may have did it?
: Thanks,
