But ask an arborist or an entomologist and the story is a little more prosaic. The liquid falling from a Crape Myrtle tree in Fresno, CA is louse poop. The plant lice that have infested the tree are known as aphides, explains an expert:
“The aphides will suck the sap, the sap goes through the aphid and then it is a honey dew excrement from the aphid, and it gets so heavy in the summertime that it will drip down.”
Watch the sick, the gullible, and the deluded gather around the tree to try to catch some insect excrement. Fun for the whole family!
If that’s not enough for you, there’s more religious poop appreciation here.
