Hi, I'm having some bad pest issues on my cascara tree, indian plum, red twig dogwood, and red alder plants. My serviceberry and ninebark also show some damage. I have found aphids and spider mites on a few plants and have doused these plants with neem oil and pesticidal soap. Any clue who could be chewing these big holes in the leaves. The only bug that I've found looks like a fly, with an orange body, and black on the head and rear tip of abdomen.

Thank you!

my first thought turns to earwigs , nocturnal bugs that feed on most any plant at night and hide from the light during the day.

Thank you, Kurt! I haven't seen earwigs in the yard, but I think I will go hunting with a flashlight, tonight.

I find them during the day when I lift up pots or open our shed doors , they scurry away from the light like roaches.

you might have better luck finding them by kicking over any clutter or things laying around they could hide under during the day.

First, please allow me to compliment you on your hands and nails; shows you are a true gardener!!

I had some mysterious leaf damage and went hunting with a flashlight to find a small green grasshopper was doing the damage. You could have earwigs, grasshoppers, caterpillars, beetles or weevils. Although I think if it were caterpillars you'd be able to see the culprits. I think if it were slugs/snails you'd see evidence of a slime trail.

Just keep checking day and night. You might try some insecticidal soap.

Thanks for the tips, greene. I've applied insecticidal soap and neem oil. I will take a peek at the plants at night, to see if I find the culprits.

I just identified the pests: sawflies. Those are the flies with orange abdomens and black heads, in case anybody has the same problem...
