Seems like a good time to remind everyone to leave plant material in the yar=
d and not be too tidy about hauling it away.  Many invertebrates lay their e=
ggs on plants -- for example, the beautiful Argiope spiders.  There could be=
 eggs or cocoons attached to the leaves or brush   If you compost or burn th=
at material, you'll probably lose next year's creatures.
