Help from 'Muddy' Owners required! The Blue Banded Bee

From Linda Rogan of FOWSP (Friends of Warrandyte State Park):

Hi Mick,
Hope all is going well out your way.  The cool change has certainly been
welcomed.

I would like to utilize Warrandyte Chat to let people beyond FOWSP know
about a Blue Banded Bee project we are starting at the nursery.  We are
making nesting blocks for these bees that dig holes in the ground in order
to nest.  It will be very helpful if we can acquire some material from
current Blue Banded Bees nests to rub on the bricks and attract the bees
with the smell of others.  They are nearby as they do visit many of the
flowers in the nursery. I have been told that it is not uncommon for these
bees to next in the walls of mud brick houses.  My plea is that anyone who
is aware of Blue Banded Bees or other native bees on their porperty, contact
me if they are happy for me to come and take a little of the material (just
the loose diggings and frass) for our project.  I have attached a photo of
the bee so people will know what they are looking for.

Thanks,
Linda
