Hi all,

My cucumber seedlings were doing great up until about a week ago, when leaves started yellowing and dying. Before everybody guesses bacterial wilt, I did the gooey yellow stuff test from a cut leaf stem and there is no such gooey substance.

I also found a bunch of these bugs around the tray, which don't really look like the pictures of cucumber beetles which I found online (I am in China, so maybe they look different here?). In the center of the picture is the one beetle which walks around everywhere in circles and to the left is a winged bug which might be the same species? I found a bunch of disembodied wings, but this is the first live one I found.

Anybody have any ideas on what my problem is and what course of action to take?
