Yet Another Hollyhock Pest
The yellow hollyhocks are less vigorous and more prone to insect attack than the pink or red. Case in point: many of the yellow buds are infested by this caterpillar or grub (jury still out though it looks more grub-like to me) while the other color flowers show no sign of it. I can pick out the buggy buds by the frass piles on the outside. Dissect the bud to find a smallish, cream colored larva with a darker brown head capsule. Cannot be, I refuse to believe this is the larva of the hollyhock weevil because the adults are so much smaller than this. And, it looks nothing like tobacco budworm which would be a likely suspect.
