Q.What Pest Is This On My Indian Hawthorn

Zone Inland San Diego County, CA | tkblizard added on November 3, 2020 | Answered

Hello. I have tried several places to find an answer – hope you can help! I have a large bank (10 ft tall by 20 ft long) of old (>18 years) Indian Hawthorn next to my house (maybe 5 individual shrubs). This summer noticed what I thought might be a virus attacking the leaves, but now think it is an invert. One garden store suggested chili trips, but from what I’ve read that doesn’t really match and they don’t look like thrips. All leaves can be infected (old and new), they are losing color or maybe chlorophyll in a “mined” type of way but no pathways. There is some spotting but doesn’t look like the typical spot this species gets. The inverts look a bit spotted to me. Dropping leaves too. See photos for more detail – want to know if they can be saved or should I take them out so they don’t infect the rest of the yard (many other Hawthorns too).
