<font size=3>I've often wondered that too, Peter. There must be an
advantage for them but it difficult to imagine what it is!! (I collect
them &amp; scatter them back on our lawn.<br>

I picked up about 100 live earth worms from the asphalt in front of the
house. We have about a 50ft x 80ft parking area that slopes down to a
brook from a small flower bed in front of the house. At this time of the
year after fairly heavy rain dozens of worms from a few millimeters to
about 15 centimeters leave the bed and start off across the paving. They
are accompanied by what appear to small millipedes although in much fewer
numbers, also some slugs that start feeding on some of the dead worms in
the morning. <br>
They certainly don't get washed out of the bed and in fact have to get
over a lip and negotiate some pavers.<br>
I guess my question is <b>why they would leave what would appear to be a
good habitat and head out for almost certain doom</b>.<br>
Does anyone know if this is common behavior and why they do it.<br>
I'm thinking of going into the bait business.<br>
Thanks.<br>
