- What shape is the damage: round holes, only veins left, white trails, or a pale stippling?

- If nothing is visible by day, check at night or early morning for cutworms and slugs.
Most likely causes
From the pests and diseases recorded for this plant, the ones whose symptoms match, most serious first. Symptoms alone rarely confirm a cause, so use the linked page to check the signs and treatment.
Tea Tussock Moth
Orange-brown larvae line up in colonies on leaf undersides and eat the leaves away. Simply standing under the plant can make the skin itch from the shed hairs.

The upper leaf surface bleaches into a whitish stipple, while black tar-like droppings and the insects themselves cover the underside. As it advances the whole plant looks whitish and growth declines.

Fine white stippling spreads across the upper leaf surface, and the leaf eventually whitens and dies back. In heavy infestations fine webbing appears on leaf undersides and shoot tips.

What other growers did about it
A page like this one can tell you what azalea pests and bug damage is and what to try. What it cannot tell you is what actually happened to someone who had it on the same plant, at the same point in the season, and what they did next.
Gadenin is a free garden journal built around that. You photograph the plant, tag what you are seeing, and the entries line up by date for each plant you grow.
- Tag the problem and the app tells you how many other growers have logged the same thing on the same plant.
- Growers who make their records public can be followed, so you can read what they did and how it turned out.
- Next season your own entries come back at the same point in the year, so you check the plant before it starts.
Free on iPhone. Recording, tagging and reading public records cost nothing.
