So, I think every night there has been a Yellow Jacket that is feasting on my Tiger Bark ficus. I keep finding leaves that are half gone with rough edges where the missing part is. I've seen one eat nearly half a leaf on my large olive tree. I wouldn't care except it's far more noticeable on a bonsai. Should I spray with Neem or, does anyone have suggestions for how to protect against larger bugs that eat leaves?
 
Bees are really sensitive to Sevin.

Wasps (and yellow jackets are wasps) don't eat plant material. They are predators who eat other bugs. They also seek out moisture and sugar this time of year. You're seeing the wasp, but it is probalby eating the critters who are eating your tree, or after the sap that is produced by the wounds.

Yeah....that sounds more like it.
 
i sadly had to move two humingbird feeders because yellow jackets.

the birds are ticked.

they say put a grape jam trap away from where you want them, another great tool is
boric acid powder traps. i might employ them next year in spring if they are trying to
make nest around my place again

I'm telling you guys, they eat leaves. I wish I had taken a video. A yellow jacket did this , it was there for several minutes just chowing away on this leaf.

Can't say I've ever seen a Yellow Jacket or anything of the sort eating leaves....weird.

Is that a common thing that I've somehow missed my whole life?
I was super surprised when I saw it. I've read they do eat sap, so maybe it got carried away. Here are some pictures of my ficus though. Could be something different. I thought they were old pruning sheer cuts at first, but they keep appearing

No way that that is damage from a yellow jacket. They do eat sap but that's the sugary stuff from tree wounds (like maple syrup).
Ficus sap is nasty.
Besides the can't make a cut that straight.
 
Look up "leafcutter ant" and compare leaf damage. Leafcutter ants work at night and damage leaves. Yellow Jackets will eat starches like sap, nectar, etc. BUT THEY DO NOT TYPICALLY DAMAGE leaves doing so. They are most likely "cleaning up" after the ants' work.
 
Another possibility are leafcutter bees--they're not wasps and they make mostly circular cuts on leaves, not straight

Okay, so after looking up Leaf cutter ant, "bee" also popped up in possible google searches. I searched Leafcutter Bees, and they do exist in California, though the cuts don't look perfectly straight. I guess they cut leaves and take them to build nests. I need a night cam to see what kind of precision insect is performing laser cuts on my Ficus leaves.
