My local nursery told me that the damage being done to my sandcherry and
weeping cherry trees are being done by japanese beetles. I've fished a few
out of the pool and I know what they look like, but all the time that I
check the trees, never have I seen one on or near them. Do they come out at
night? How can I not see them? We sprayed a chemical that the nursery sold
to us but I can't tell if it's working. Any suggestions or info on these
little critters is greatly appreciated.

Just google "japanese beetle trap". There are multiple models of them-- but
they all boil down to a
pheromone lure over a bag. The beetles fall into the bag and can't fly out
again. I bought mine at
Wal-Mart, but I'm sure you can get them anywhere with a garden center.
Placement is extremely important with the traps. They need
to be placed away from the area of the plants that the
beetles bother (in my case Dahlias). They do such a good
job of attracting and catching the beetles it is NOT
necessary for a the neighbors to have them (unless you have
really a lot of beetles). Since I started using them I have
very little damage to my Dahlias.
The one I have (don't remember the brand-- maybe Ortho?) says that it controls
1/8th square acre.
The way I figure it, I can't kill every june bug in my area, but at least the
thousands I do kill
are off my plants and will not be laying eggs.
I've read that, too, but all I know from personal experience is that my canna
lilies, which were
being utterly destroyed by the beetles, are now virtually beetle-free and the
flowers actually stay
in bloom instead of being eaten away as soon as they bloom. I live in a rural
area filled with open
fields and woods, so placing traps everywhere wouldn't be feasable.
The few japases bettles I see out here don't bother my I.Canna ( canna are
NOT lilies ), but I also watch out and distroy their grubs when I find them.
Their's Milky Spore which you can put on the ground which helps kill the
groubs from the JB's.

Same here, they are most active around 11am to 2 or 3pm. I have caught
literally 2 full quarts of them so far. Picture 2 quart mayo jars full.
THOUSANDS! This year is the worst in 3-4 years.
