My Azalea leaves are being eaten to death !

I have noticed today that my evergreen Azalea leaves are being badly eaten. It looks as though it has been caterpillars but I can find no evidence of them. It could be anything really as I'm pretty clueless with pests & the like. Does anybody have any idea what the hungry critters could be & how I can eradicate them ?
I could post a picture of the plant if that would aid identification.
Cheers.

 

Pictures are always useful, Naepace!

The usual culprit at this time of year for nibbling any leaves is the vine weevil.

Is this

the sort of damage you're talking about?

 

Not really mate, I'll get a pic up tomorrow.
Cheers.

 

If it's not that, a picture would definitely help!

 

With Azaleas the first thing that comes to mind is the dreaded Vine Weevil. Check the soil around the root for grubs about a half inch long, white with a brownish head they will be semi curved. However it will not be these that caused the damage but their parents so also look on the ground for beetle-like insects with a small head and a larger, spotted body. If you find either grub or adult they should without doubt be killed. David.

 

Hopefully that will help.
Dave I'll examine the ground in the morning, too dark up here in Scotland now.

 

This is the first growth of my 'Day Lilly', also being dined upon. Again there is no obvious sign of infestation. Slugs perhaps ?

 

Hi Naepace, to me the plant in the first picture looks as if it is suffering from scorch damage, this happens when water droplets stay on the leaves and act as a magnifying glass for the sun or for cold winds, the second pplant looks to be suffering from slug or snail damage. David
