Isopods are omnivores or scavengers feeding on dead or decaying plants or animals. Some may eat live plants.
Color varies from dark gray to white with or without pattern.
Isopods breathe with gills, so they are restricted to areas with high humidity, under rocks or logs, in leaf litter or in crevices. Some species are nocturnal.
Some species, roll up into a ball when disturbed. Eggs (up to 100) are held in broad pouch on female. Juveniles look like adults and are soon liberated from pouch. Molting is in two stages. First the back half molts, then two to three days later, the front half molts. Coloration of both halves may be different at this time. Many species are fast walkers, but can be easily observed when held in the palm of the hand.
Impact on the Ecosystem ...
Positive
In their immediate vicinity, isopods do minimal soil improvement. Isopods are also a food source for other animals.
Negative
In greenhouses and southern states, large populations can eat and damage plants.

Yeah, roly-polys are cool. I've heard people say that they eat some plants, but I've never found them to be a problem. And, they are fun to play with, lol. One of the few bugs I'm not afraid of.

Most of the time, they lounge about under leaf duff to eat detritus at night, but recently they have brought havoc to my shade garden, eating Hellebores, Hostas, Hedera, etc.
Their activity in eating at Iris rhizomes is like nefarious swiss cheese. Most of my life, I had never seen one further than and inch off the ground, but I have seen in the past two years specimens actually climbing up stems to chew leaves.
Yet another colorful perk to being a gardener?
Areas I have seen of greatest density are moist wood mulches covered by unrooting groundcovers like dianthus, where they are so thick, the soil is heaving with them.
I have seen them fall to the pesticide called "Bug-Getta Plus," so it is time to bring out that old bottle again.

I lost three Campanula "Blue Clips" to these bugs practically overnight. I'm finding very large numbers in areas with shredded hardwood mulch. I'm beginning to wonder if they came with the mulch. In the past I've not viewed these as garden foes, but in large numbers I need to try to control them.
Otherwise, I used to love watching them roll up when I was a kid.

I've loved these little guys since I was little! For some reason we always called them potato bugs. There was a seemingly endless supply. No matter how many times we turned over a rock, there were always more to be found. We kept them in jars as pets and teased them into rolling up, then holding perfectly still, waiting for them to relax. It was just facinating.
In my garden they can always be found in the compost heap and at times in the vegi garden were they do minimal damage to the carrots.

When I was a kid we use to play with these like crazy! Even made little down hill coarses for them to roll on. Rollie-pollie! I mentioned this bug to my girlfriend just now "I loved rollie-pollies!" I've never had any trouble with these guys invading my gardens, they all hang out under the logs and bushes.

I used to like these bugs as a child, but now that I'm a gardener they drive me crazy. They ate halfway through the trunk of my 10 year old butterfly bush, now all that remains is it's beautiful memory.

I used to love playing with these bugs as a kid, but now they gross me out. I was weeding today, and after Id pulled some, I looked at the ground and there were tons of them scurrying around! *shudders*

Never had any problems with roly-pollies - used to and still like them as I think they're cute. One of the bugs I do not disturb as they never bothered my garden. Has anyone actually caught them in the act ? :)
I was under impression they do not feed on plants and feed on rotting leaves and etc.. from the ground - unless they have mutated due to toxic waste LOL ...

I also was under the impression that they not only do no damage to vegitation but that they are helpful to soil condition. When we harvest our compost, we find zillions of them, which my kids love. Other than in the compost pile and under rocks, I never see them at all.

Last year I noticed that the numbers of pillbugs and sowbugs in my garden had increased. Over the winter I added lots of shredded mulch to my flower beds. The early spring was a damp one and I have pillbugs and sowbugs everywhere! The ground moves with them and they are eating not only dead leaves but live plants. I hate to put poison out because I have birds that I feed . What can I do?!

I was a roly-poly loving kid, like most people, and now I have a roly-poly loving daughter.
There are so many of these little critters in my yard that I need to be careful not to squash them at night (constant patrols of them on the sidewalks). I often dig up huge clusters, and my compost pit is likely half compost and half roly-poly (fine with me, I have too much compost anyway).
The only plant I've seen them particularly flock en masse to is bindweed (though they will hide out under anything over-grown). If I could find evidence that they are eating it, as opposed to living under its shade, I would give them a raving positive. (I can at least daydream about them eating the roots!) All I know for certain is that when I dig up bindweed, I tend to send roly-poly colonies scurrying.
For all of their numbers and ranging, I haven't seen one on a garden plant yet.

Pillbugs and sowbugs seem to rarely mix with each other much - I have seen areas with mostly pillbugs and there's my yard which have nothing but sowbugs but no pillbugs. Pillbugs seem to be more of a southern species, being found in Iowa and Wisconsin at the edge of their northern range in the Midwest. Sowbugs seem to be more of a northern and central US species. To tell the different between the two - pillbugs will roll up when you handle them while sowbug will flee without any attempt to roll up, even if they are put on their back.

According to a UC Davis study, roly-poly bugs not only eat decomposing matter at ground level, but will also climb up some plants to eat stink-bug eggs. Since stink bugs do eat all sorts of vegetable plants and other live vegetation, maybe they're what's really eating your plants and the poor roly-polies are just taking the blame?

Helter Skelter! My garden is living (or dying) proof that these scavengers will eat any and everything living or dead in a garden! As a non-bug killer, I have been finally pushed over the edge and squish them with impunity. They eat flowers, fruit, vine and root. Nothing is off-limits to these little armored terrors. Yes, I have seen them do it. Perhaps it's just a problem for the humid south, but they are a definite garden pest around our house.

There seem to be millions of these things in my back yard! I see them all over the place but especially around the brush/compost pile. After a good rain, there will be 100s about a foot up around the base of my oak tree. I haven't noticed them eating my plants, but with so many of them living here, I figured it was time to do a little research on them.

I never thought they harmed plants. They have destroyed most of my vegetable garden. I thought a larger critter was eating everything but couldn't figure out the culprit. I was covering everything in mesh and replanting. They made me look stupid. I think it is the cedar mulch they like to live in.
The "Roly-Poly's" have been providing entertainment for my children all summer, and I thought they were harmless. Last night I caught one chewing a whole in one of my strawberries - I've been wondering who the culprit is. As a new gardener, any advice on the most natural bug deterrent to save my garden? I've used a citrus spray on ants and box elder bugs in our yard with success, but have been hoping to avoid using anything in the garden.
Caught bug in 'the act' eating my artichoke plant. I never liked then even when I was little because my brother used to throw them at me- now I really don't like them. Do they have any predators that eat them but don't harm graden?
