I have seedlings started indoors in polystyrerne cups, under lights: tomatoes & peppers up about 1 inch but not yet with true leaves. This morning I find about 30 percent are nipped off 1/4 to 1/2 inch above soil level. In most cases the young first leaves are gone. Completely vanished - just a stub of stem remains.
I see no sign of whatever pest has done this (apparently overnight when the lights are off.)
Can anybody make an educated guess, what beastie would this be? And what can I do to protect the rest of my seedlings - please be quick! - as well as thwart the pest in future?
