That can kill caterpillars. We recommend that everyone take photos when something goes wrong. Photos often tell the whole story when someone with an experienced eye sees them. Dettol contains ingredients that are deadly to caterpillars.

Thank you so much Edith!!! Great info! What is causing my blackmail cats to borrow in the dirt? And I assume die?
I think auto-correct took over your keyboard! Best wishes, Edith Like Like. Leave a Reply Cancel reply Enter your comment here Within a day both were lethargic and then lifeless and ended up in that upside down V which I have since read about on here.
I am guessing something is wrong with the plants I bought. Can I try and save the plants somehow or should I start over? There are two teeny tiny cats about now…. I had a caterpillar die in a similar fashion to the one you described last year and it was after a long fight with another and one of its front filaments got torn off. Mine was a big caterpillar. I remember reading at one point, that in conditions of stress, certain soil conditions etc, the plant itself may become more toxic?
Is this speculation or a possibility? Speculation as far as I know. Cardenolide levels vary wildly between different species of host plant, different plants in the same species, different parts of the same plant, and at different times in the same plant. I had a caterpillar die a couple of months ago in an unusual fashion. It was in a castle with 4 others which I had on display at a local preschool.
The other four were apparently fine, but the fifth turned black and rigid, like a twig. But the sad reality is that monarchs lay hundreds of eggs when only two are needed. Big bugs have little bugs upon their backs to bite them.
The little bugs have smaller bugs, and so on ad infinitum. The tree from last year became host to so many aphids it succumbed so I pulled it out and let a new one grow up which this last batch of caterpillars are living on.
I did wonder earlier if the bacteria could have been present in the potting mix given that potting mix usually comes with a warning label about handling it, for the very reasons of bacteria sometimes propagating in the soil. There were no casualties this morning, and the sickly four are still alive, albeit sluggish. Still producing frass. I do not know if the catties will get over their lethargic state or not.
That will be an indicator of whether or not they have also been affected. And it seems that Bt is the closest match to what may be going on, so thanks for that information.
Some good observations from you, and the fact that the smaller caterpillars only are affected is interesting, and although toxins could be a suspect, a poisoned caterpillar reacts by dropping from the plant and writhing on the ground. The fact of them hanging in an inverted V is typical of a viral disease such as NPV but the skin ruptures and the contents discharge, the disease spreads rapidly as Char mentions, plus the larger caterpillars would become infected also.
The disease is soil borne and is also produced as the most widely used bacterium for pest-insect control in agriculture. Could your plants have been subject to any wind borne spray? The residue on the leaves sounds a little suspicious. The progress or demise of the larger caterpillars should perhaps pinpoint the problem further. Keep us posted.
There is a very light fungal residue on some of the leaves, I have since discovered — from water that has dried out on the leaf. I double checked back with Kings Garden Centre, re. He reassured though that there had been no sprayiing. Ones of a slightly larger size that seem to have been similarly affected, are a little more responsive. I have brought in leaf from an outside plant.
The main smell seems to be the plant itself there are a lot of blossoms, and it was almost overpowering when I first brought it home! Not much diarhhea — even some of the sickening ones still appear to expell frass, although I have noticed some small spots of diarhhea.
This could also be vomit. Sluggish — yes. Responsive to breeze though — seems to prompt more activity. I think all of them seem a bit sluggish, including some of the larger ones — although that might be my imagination. Inverted V. Have only noticed a couple in full V — usually the smaller ones. If you are rearing some species, such as tiger moth caterpillars, it is good to add a few drops of moisture to keep them from drying out too much.
Do caterpillars fight with each other? Two monarch caterpillars fighting and violently striking each other over feeding territory! With limited food on this particular milkweed stalk, these two monarch caterpillars engage in a territorial battle, striking each other repeatedly.
Why is my caterpillar curled up? Caption: A monarch caterpillar assumes the defensive position by curling up into a tight ball. Unfortunately for the monarch larva, this is about the extent of their defense against predators. Many stay away because bright stripes indicate their toxic nature. However, that is not true of the caterpillar's first meal. Why are my monarch caterpillars not moving?
Shed its skin. When it is time to do this, they often will go to find a nice, quiet place and stop moving, sometimes for around hours or so. What do caterpillar eggs look like? As seen in these egg photos, many eggs start out light colored like an off-white to a yellow color then change to a dark color or black before the caterpillar comes out. Most caterpillars hatch out of the eggs in days. It can vary depending on species and other conditions.
What happens if a caterpillar does not make a cocoon? This can happen if for whatever reason the caterpillar is unable to stop producing juvenile hormone JH , which maintains the larval or caterpillar stage. She holds a B. Marina has worked with a number of publications involving animal science, behavior and training, including animals.
Black Death — Despite having a singular name, people use this term to describe two different diseases. The first is a bacteria in the Pseudomonas family. The second is a virus known as nuclear polyhedrosis virus. Pupa afflicted with this illness will turn black and begin to liquify inside.
Tachinid Fly Infestation — When pupa infested with this parasite die the worms of the fly emerge from their chrysalis. You will also see white strands of silk hanging from the chrysalis. Chalcid Wasp Infestation — These wasps wait for the chrysalis to form and then lay their eggs inside. This infestation is fatal to the chrysalis.
You will be able to see numerous black dots on the surface of the chrysalis from where the wasps deposit their eggs.
Various Toxins or Poisons — Caterpillars can come in contact with a number of different toxins.
