lily beetles

[meltedmarsbars]

Lily beetles are bright red and very hard to find - they drop off upsidedown as soon as you go near them. It is easier to find their droppings - black slimey bits.

Lily beetles used to be notifiable - not sure if they still are, but with stealth and cunning you can kill the blighters. Squash'em.

Lily beetle larvae they feed on the underneath of the leaf. The adults are big red beetles.
