Hi,

It's definitely something eating the leaves, and AT NIGHT. That's why when you inpect the plant during the day you don't see any insects. Very likely grasshoppers or praying mantis, come out at night with a flash light and see. What city/state are you in?

Good luck,

Newgen: Im in Houston, Tx. Btw, AT NIGHT??? I will come out tonight to see whatever did hurt my tree that much. Gonna post an update of the "inspection" tomorrow morning. Thank you so much newgen. Should be any other possibilities in this case?

Hi New, after 1 hour of standind and fightin' with the ants next to the logan, I still couldnt find anything. What should I do before those monters finish eating all the leaves also on my canistel and white sapote? Thanks.

Did you see any new leaves get eaten, since your last picture? If there are no NEW damage, it may have been a 1 time episode. Looking at your photos, it looks like it could be catepillars too. I have 3 longan trees in-ground, sqirrels came and ate all fruits on 2 of them. The 3rd tree I had to put up a chicken-wire enclosure around to preven them buggers from getting to my fruits. On my chilli pepper plants, I counted 11 big, fat catepillars chowing down on the leaves. So look for them too. Keep me posted on what you find out.

I think my lychee tree has the same problem. definitely not a 1 time episode. could it be some kind of bacteria?
