Do Caterpillars Eat Blackberries

Caterpillars do eat blackberries, and they can be a real problem for your blackberry plants if you’re not paying attention.
 
If you’ve been asking yourself “do caterpillars eat blackberries?” the short answer is yes, certain caterpillars love munching on blackberry leaves, buds, and even the fruit itself.
 
It’s not just one type of caterpillar either, several species find blackberry plants irresistible.
 
So if you’ve noticed chewed leaves or half-eaten berries on your blackberry bushes, caterpillars are likely the culprits.
 
In this post, we’ll take a closer look at whether caterpillars eat blackberries, which caterpillars are most likely to do it, and how you can protect your plants.
 
Let’s dig in.
 

Do Caterpillars Eat Blackberries?

Yes, caterpillars eat blackberries, and they’re actually pretty fond of the entire blackberry plant.
 
Here’s why blackberries are such a tempting target for these hungry little critters.
 

1. Blackberry Leaves Are Tender and Nutritious

Blackberry leaves are soft, juicy, and packed with nutrients, which makes them an ideal food source for caterpillars.
 
Caterpillars need to eat almost constantly to fuel their rapid growth, and blackberry foliage gives them exactly what they need.
 
That’s why caterpillars eat blackberries’ leaves so aggressively, sometimes stripping entire canes in a matter of days.
 

2. The Fruit Is Sweet and Easy to Reach

Caterpillars don’t just stop at the leaves, they’ll also eat the blackberries themselves.
 
Ripe blackberries are soft, sweet, and full of moisture, which makes them an easy meal for a caterpillar that’s already living on the plant.
 
If you’ve ever picked a blackberry and found a small worm-like creature inside, that’s often a caterpillar or larva that got there before you did.
 

3. Blackberry Bushes Offer Shelter and Food

Blackberry bushes are dense and thorny, which makes them a perfect hiding spot for caterpillars.
 
They can feed on blackberries, hide from predators, and complete their life cycle all in one place.
 
So when caterpillars eat blackberries, they’re not just feeding, they’re basically setting up camp.
 

4. Certain Caterpillars Specifically Target Blackberries

Some caterpillar species are especially drawn to blackberry plants.
 
The raspberry sawfly larva, for example, looks like a caterpillar and feeds heavily on blackberry and raspberry leaves.
 
The leafroller caterpillar also eats blackberries by rolling itself inside a leaf and nibbling away from the safety of its little shelter.
 
And the dreaded codling moth larva, while more famous for apples, will happily eat blackberries too when they’re available.
 

Signs That Caterpillars Are Eating Your Blackberries

So how do you know if caterpillars are eating your blackberries?
 
There are a few telltale signs to look out for.
 

1. Chewed or Skeletonized Leaves

If caterpillars eat blackberry leaves, you’ll notice irregular holes, jagged edges, or leaves that have been stripped down to just the veins.
 
This skeletonized look is a classic sign that caterpillars are feeding on your blackberry plants.
 

2. Holes in the Berries

When caterpillars eat blackberries, they often leave small holes or tunnels in the fruit.
 
You might also find frass, which is caterpillar droppings, near the berries or on the leaves below.
 

3. Rolled or Webbed Leaves

Some caterpillars eat blackberries by rolling leaves around themselves for protection.
 
If you see leaves that look curled, folded, or stuck together with silk-like webbing, that’s a strong indicator caterpillars are living and feeding there.
 

4. Visible Caterpillars on the Plant

Sometimes the simplest sign is just seeing them.
 
Check the undersides of leaves, the tips of new growth, and around the fruit clusters, especially in the early morning or late evening when caterpillars are most active.
 

How to Stop Caterpillars From Eating Blackberries

If caterpillars are eating your blackberries and you want to stop them, you’ve got options.
 
Here’s how to protect your plants without going overboard.
 

1. Handpick Them Off

The simplest way to deal with caterpillars eating blackberries is to pick them off by hand.
 
Wear gloves, check your plants regularly, and drop any caterpillars you find into a bucket of soapy water.
 

2. Encourage Natural Predators

Birds, parasitic wasps, and ladybugs all feed on caterpillars that eat blackberries.
 
By encouraging these beneficial creatures in your garden, you can keep caterpillar numbers in check naturally.
 

3. Use Bacillus Thuringiensis (Bt)

Bt is a natural bacteria that specifically targets caterpillars without harming bees or other pollinators.
 
Spray it on your blackberry plants when you notice caterpillars eating the leaves, and it’ll stop them without chemicals.
 

4. Keep Your Plants Tidy

Remove debris, prune overcrowded canes, and clear weeds around your blackberry bushes.
 
This reduces the hiding spots where caterpillars that eat blackberries like to shelter and breed.
 

5. Inspect New Plants Before Planting

Always check new blackberry plants for eggs or caterpillars before adding them to your garden.
 
It’s a simple step that can save you a lot of trouble down the line.
 

So, Do Caterpillars Eat Blackberries?

Caterpillars do eat blackberries, and they can cause real damage to both the leaves and the fruit if left unchecked.
 
But with a little vigilance and a few smart strategies, you can protect your blackberry plants without harming the good bugs in your garden.
 
So the next time you spot a chewed leaf or a hole in your berries, you’ll know exactly what’s going on and what to do about it.
 
Whether caterpillars eat blackberries in your garden or not, now you’re ready to handle it.
