So one of the goals for The Bees’ Needs is to provide nesting sites for our native solitary wood-nesting bee species. If block 131150 is any indication, it looks like we are doing pretty well.

Here’s the story –

In 2013 block 131150 had 7 completed Osmia lignaria nests in it. The offspring emerged a few weeks ago and many renested in that same block. There are, in fact, 20 completed Osmia lignaria nests in this block now. AND – the bees have moved into the new 2014 block, 141050, that our returning Citizen Scientist has placed in her yard.

With a three to four fold increase in Osmia lignaria nests in just one year at this Boulder residence, these bees are having a great year.
