My garden lilies are being eaten by a orange/brown grub. They start eating the bottom leaves of the stem and work their way up the plant. as soon as you touch them they just turn to a jelly type substance. Can anyone help please.

Welcome!

Can you post a picture of the insect so we can identify it and better suggest options for control? I'm assuming it is not this pest of lilies pictured here:

Larvae of the lily leaf beetle.

There are pictures of mostly the adults in the link I gave earlier.

Brownr26, I do not have much experience with them, however, in The North American Lily Society Quarterly - which I received today there was an article on just that, authored by Paul Siskind. Your options: Basically, A.) handpicking - then squeeze the little buggers, or just flick them into soapy water(somewhat effective method of control...assuming you are very vigilant!. B.) Diatomaceous Earth - aerial sprinkle on plants and ground -at least according to this article, limited efficacy. (better at controlling the larvae than the adults) C.) Neem Oil - approx 0.003% by volume mixed a half teaspoon per 28 ounces of water. This study indicated a sizable reduction in larvae and adults with this method. D.) Sinosad (Spinosyn A and spinosad D) - approx. 0.0078% by volume by volume prepared from concentrate. "This resulted in the best results over the course of the season if you are using a single control method."

Perhaps some of the other folks on this forum that have more experience with the little buggers can chime in and describe what works for them.

Brownr26: Welcome to the Forum from "across the Pond," from another Colony! LOL. I am a huge Oriental Lily grower. SOOBY nailed it already, and others contributed, the pictures shown are of the individual, well hatched "Lily Beetles" and will turn brilliant red if you have not squished same already. There actually are two treatments for "Lily Beetles"! Here is my experience. Early Spring as soon as the lilies start to poke through the soil or shortly thereafter, get out there with your strongest eyeglasses (only to spot/detect the little btd's when they drop to the ground-which they will when you try to pick them off) and squash them. I have this theory that if I leave squashed lily bugs everywhere, eventually the birds might learn to do it for me-just a theory! LOL. Secondly, I participated last year in a Canadian/US study introducing a tiny parasitic wasp, under controlled conditions, to one bed of Oriental lilies.The wasp, the size of a black fly, attacks the first blackish looking goo on the underside of the leaves (from which a bunch of those teenage specimens you pictured emerge), effectively parasitically (better way to phrase that) killing the beetles long before the stage at which your pic illustrate. I have to say, there appears to be a decided difference in the number of Lily beetles in that bed! Way fewer! Initially, pick them off as others have suggested! Cheers!

For the first time, here in central Michigan I have lily beetles -- the larvae are gross! They chewed up 1/2 of a easter lily hybrid in one week. I've gone on patrol for more damage, but I'm looking for backup. Thank you for the neem and spinosad information Frank! I hope the parasitic wasps make it to Michigan!
