The name bloodsucker beetle seems intimidating, but common red soldier beetles are not as bad as they are made out to be. Learn all about them in this article.
Soldier beetles get their name due to the various color combinations of red-and-black markings on their bodies which look similar to a soldier’s uniform.
Speaking of red bodies and markings, there is a beetle that people think is very dangerous because of its appearance; this insect is called the red soldier beetle.
They are also known as bloodsucker beetles. Sounds frightening? Well, not really.
They are not at all dangerous. But then why are they called bloodsuckers? Let us find out more in this article.
What Are Common Red Soldier Beetles?
What Do They Look Like?
The red soldier beetle – Rhagonycha Fulva, is a medium-sized beetle with a narrow and rectangular body.
Red soldier beetles can grow up to 0.5 inches in length and are often mistaken for wasps.
These beetles have long antennae and bright red spots on their wing covers, with a black patch on the edge of the wings.
Although they are called red soldier beetles, they come in different color combinations, including black, orange, and of course, red.
Adult soldier beetles are easy to spot against the backdrop of flowers like daisies and hogweed during the months of June to August.
The adults don’t survive very long and spend most of their lives mating. The soldier beetle larva looks like a long worm and is very thin.
What Is Their Habitat?
Red soldier beetles can be found in open-structured flowers like hogweed, daises, and cow parsley. Since they fall from flower to flower, they are considered decent pollinators.
Grasslands, hedgerows, parks, and woodlands are the ideal red soldier beetle habitat.
The populations of red soldier beetle species are distributed all across Anatolia. They are also found in England, North America, and parts of Canada, like British Columbia and Ontario.
Life Cycle of Common Red Soldier Beetles
The life cycle of soldier beetles starts with the mating of male and female adult soldier beetles.
The males find the female by getting attracted to pheromones.
These insects undergo complete metamorphosis and show four stages: eggs, larvae, pupae, and adult soldier beetles.
After mating, the female searches for a secure spot in the topsoil to lay the eggs.
Within a week, these eggs hatch.
Once the larvae emerge, they shift to nearby wooden debris or loose barks to feed enough to reach the pupation stage.
Fascinatingly, these larvae can survive for 1-3 years. Soon afterward, they begin pupating in an underground cell.
From the start of July, you spot the adult soldier beetles emerging and flying around. Within a few days, these adults will mate and die.
Do They Really Suck Blood?
You might be forgiven for thinking that the red soldier beetle sucks blood; after all, they are commonly called “bloodsucker beetles.”
But what if we tell you these beetles are harmless and do not suck blood? Yes, it’s true – there is no need to be scared of these red beetles as they do not suck human blood.
They are called bloodsucker beetles due to their red-colored bodies.
Are They Poisonous/Venomous?
Most species of soldier beetles, including the red soldier beetles, are gentle insects. They do not have a stinger and cannot sting.
Yes, the name “soldier beetle” sounds like it is an attacking army, but they are not poisonous and will not cause any injury or illness to humans. They aren’t even aggressive!
However, when threatened, these insects emit a fluid that makes them unappealing to predators. This liquid smells bad, and you would not want to be around that smell.
Do They Bite or Sting?
No, red soldier beetles do not bite or sting. These insects are gentle and will mostly lie down and play dead when they come across humans.
Also, we mentioned in the previous section that they are poisonous. The only concern is the foul-smelling liquid they emit.
Are They Beneficial?
These red and orange beetles seem intimidating, but they are highly beneficial insects.
Because they love to be around flowers like daisies, marigolds, hogweed, and other flowers, they are considered pollinators.
Adding to that, these insects are great for natural pest control.
Although the adults live for only a short time, they are good hunters of aphids that cause damage to valuable plants in the garden.
Even the larvae of this insect is known for predating grasshopper and other pest eggs.
Having a few of them in your garden will decrease your dependence on pesticides and will work wonders to maintain the fertility of the soil.
How To Attract Them To Your Garden?
As we already mentioned, the soldier beetle family is excellent for keeping unwanted pests away. Many gardeners would like to attract them to their yards and fields.
Here are some methods to lure them into your gardens:
Having a variety of flowering plants in your garden is an excellent way of attracting red soldier beetles. These insects are often spotted roaming and mating around flowers.
You will find them feeding pollens and nectar around flowering plants like marigolds and daisies. If you have a well-blooming garden, red soldier beetles will surely come flying toward it.
Larger insects, lizards, and birds hunt down red soldier beetles. If these organisms are regular visitors to your garden, the beetles will stay away from that spot. Keep the area predator-free for best results.
Frequently Asked Questions
What does a red soldier beetle eat?
Adult red soldier beetle adults live for short periods and are rarely seen eating anything. They spend most of their time mating.
In some cases, you will find them eating pollens and drinking nectar from flowers like hogweed, daises, and marigold. They also hunt aphids sometimes.
Are red beetles poisonous?
No red soldier beetles are not poisonous. They can look a little intimidating due to their peculiar red bodies, but they do not attack.
These insects don’t have a stinger either. The only concern is they release a foul-smelling fluid whenever they feel threatened.
Do soldier beetles bite or sting?
Soldier beetles are gentle creatures from the beetle family. They are non-aggressive, and they barely bite. Adding to that, these beetles don’t have a stinger to use for attacks.
If a soldier beetles spots danger, it releases a foul-smelling liquid from the body, which makes them appear unattractive to the predators.
Can soldier beetles hurt you?
Soldier beetles are gentle insects, and they barely hurt anyone. If they come across a threat or a person, they lay on the ground motionless to play dead.
In some cases, they release a liquid from the body which smells pathetic and will make you smell the same.
Wrap Up
Red soldier beetles are often misunderstood as viscous blood-sucking insects.
The red-colored bodies and the name bloodsucker beetles only add to the fire. But these creatures are quite gentle and harmless.
However, make sure that you don’t touch them, especially when they emit that foul-smelling defensive liquid.

I wish I had found your site earlier!
I have numerous of these beetles on my young white spruce…are they sucking the spruce sap? I squeeze them between my fingers until they die…sometimes squeeze two attached – guess they die happy…do I need to be concerned? Should I use the malathion?
They’re not hurting your spruce as they are a beneficial insect, likely eating the aphids on your spruce tree. Don’t spray them, let them live.
