While cutting across Russell Square in London, i stopped to have a look at the bug hotel.
Russell Square is surrounded by hotels for people, so it seems appropriate that bugs should have their own "hotel" in an effort to promote biodiversity.
Bees might make their home inside hollow reeds. Dead leaves and bark provide homes for other insects. My insect "hotel" at home is a dead tree. One dead tree can host 52 different creatures, so we keep several dead trees standing in the woods near our house.
Our own dead bodies can host several creatures. One friend who died last fall had a green burial for this very reason. Her shrouded body was not embalmed and was placed in a cardboard coffin that was decorated by her family and friends. The coffin was then placed in a shallow grave also with several worms.
Our compost piles are excellent bug hotels. Kitchen scraps rot and become dirt, thanks to bugs and bacteria.
Life springs forth out of dead stuff.
