Rove Beetles: Basic Characteristics and Features Guide

The rove beetle is one from the beetle family and is a part of the Animalia kingdom. They belong to the Insecta class from the Coleoptera order and the Polyphaga suborder. They have this one unique characteristic that is their wings are small, and it covers only half of their abdomen and leaves almost the rest of it exposed. This is among the largest family of beetles with more than 63,000 species spread across thousands of genera. This family of the beetle was present from an ancient time with the fossils of these beetles found from as old as 200 million years back. If the genus Leehermania is proved to be a part of this family of beetles, then they will have had existed form a long time.

This family of beetles is morphologically and ecologically diverse and has many ways that they can get into your house. You can most commonly find them in terrestrial environments. One of the most popular subspecies of this family of the beetle is the devil’s coach horse beetle. The rove beetle belongs to the Staphylinidae family. There are a vast number of subfamilies of this beetle. Some of these various subfamilies are the Aleocharinae, Dasycerinae, Empelinae, Apateticinae, Euaesthetinae, Staphylininae, Glypholomatinae, Habrocerinae, Megalopsidiinae, Leptotyphlinae, Microsilphinae, Omaliinae, Neophoninae, Micropeplinae, Olisthaerinae, Oxyporinae, Osoriinae, Paederinae, Oxytelinae, Piestinae, Phloeocharinae, Protopselaphinae, Proteininae, Pselaphinae, Scaphidiinae, Pseudopsinae, Tachyporinae, Trigonurinae, Steninae, Trichophyinae, and Solieriinae.

Rove Beetles in North America

Rove Beetles are the biggest group of insects in North America, and the small black rove beetles are common in Florida. The pests are dynamic in warm months and rest in the winter. They are nocturnal in nature, so identifying pervasions can be troublesome. Basically, they settle in rotting natural places and soil. As the rove beetles eat other little bugs, they are commonly viewed as helpful in pest control. In any case, home infestations can be tricky. They likewise cover up under leaf litter, trash, shakes, and plants. This is how rove beetles get into the house. In homes, the vermin can be found more often than not in the storm cellars. When the question of what do rove beetles eat comes up, you should know that they feed on almost everything. These pests feed on little bugs found on products and dead creatures. There are a number of other ways as to how do rove beetles get into the house, and they are through the kitchen windows, and they thrive in the garbage or any humid place in the house.

Rove Beetles’ Lifecycle

Rove Beetles in North America

Their life cycle comprises of four phases: eggs, hatchlings, pupae, and grown-up stage. The rove beetles grow quickly in the initial stages, and the adults live for extended stretches of time. The small black rove beetles from florida have various features like their laying of eggs and other habits. The eggs are laid in rotting matter and soil before bring forth. Ordinarily, they are dark or darker with thin bodies and short front wings. As grown-ups, wander scarabs are commonly littler than 2 cm long. Property holders can recognize these bugs from different creepy crawlies by the manner in which they edge their bellies upward when they run or are startled. They are unattractive when they accumulate in homes. Also, they may nibble when taken care of. To forestall meander insects, expel any rotting issue close homes. Property holders can likewise decrease the vermin’s entrance via fixing any splits or openings around windows and entryways. Property holders should look for meander creepy crawly pervasions under plants and waste receptacles inside or rocks and vegetation outside. As the creepy crawlies move rapidly, people may catch looks of them. Control invasions in houses by vacuuming up meander scarabs promptly after recognition. To adequately evacuate huge populaces, contact your nearby vermin control master.

You can find rove beetles even in Australia and other parts of the world. When you doubt as to do rove beetles fly, you should know that they have wings and can fly pretty well. They are a species that fly only when most necessary. If you want to know that do rove beetles fly, then the answer is yes. But along with that, you should also know that though they can fly they usually prefer to run to locomote rather than flying.


As it may be normal for such a vast group of beetles, significant variation exists among the species. The sizes of the beetles go from more than 1 to 35 mm, with most in the 2 to 8 mm run, and the general type of the body is stretched, with some wander insect being ovoid fit as a fiddle. The shades of these scarabs extend from red and yellow to rosy brown or even brown to dark black to luminous green and blue. The receiving wires of these beetles more often than not have 11 fragments and are fibrous in nature, with moderate clubbing in a few genera. The stomach area might be long and adaptable, and a portion of these bugs externally take after earwigs.

Some members from this beetle family like the Paederus genus which is a subfamily of the Paederinae contain a pretty dangerous vesicant in the hemolymph which is what hurts so bad when rove beetles bite. This chemical substance in their body is what irritates the skin when bitten. When rove beetles bite, you will have a condition called the dermatitis linearis which will cause irritation and even blisters on your skin. The toxin or the poison that causes the irritation is extremely vicious and even more dangerous than cobra venom.

Immature Stages: The Staphylinid eggs are usually white in color, spheroidal and spherical as well as sometimes even pear-shaped in nature. Some genera of this subfamily are said to have eggs with surface sculpting, and this helps in the identification of the eggs. The larvae are staphyliniform, which means that they are flattened and elongated in shape. In some of the subfamilies, the head is better sclerotized, and they also have a more distinct neck region. The Staphylininae and the Paederinae are the most common ones under this category. The rove beetles life cycle is quite interesting after this phase. They spin a silk cocoon inside of which they pupate and continue their life. The pupae are pigmented, obtect, and even sclerotized in the subfamily of the Staphylininae. In the other subfamilies, however, this is different, and the pupae are white, unsclerotized and even exarate in nature. The main characteristic of the rove beetles life cycle is that the immature stages of these beetles grow pretty quickly and the adult pones, on the other hand, are long-lived in nature.

Adults: The length of the adult Staphylinidae varies between 1mm to 40mm; however, most are less than 7mm. Most of these beetles have short elytra, uncovering a few stomach portions however it would be a blunder to envision that all of them have short elytra, or that all beetles with short elytra are Staphylinidae. Commonly, they are slim with short elytra and strong stomach musculature that renders them exceptionally adaptable and along these lines ready to enter slender cleft. Those that have short elytra exchange adaptability for presentation, rendering them subject to parching and ward upon sticky living spaces. The segments of their abdominal region have sclerotized plates surrounding it, and they are all connected through membranous links. The length of the body looks longer when moist and alive and on the contrary, it looks smaller in size when it is dry and dead. Some species are soil inhabiting and cave-inhabiting, and they don’t have eyes, and this has evolved. When you wonder as to what rove beetles eat, it is important to know that they feed on smaller insects and also plant tissues. The newer subfamilies even feed on the larger plant tissues.

Ecology of the Rove Beetle

These beetles are best known from each kind of living space in which beetles happen, and their eating regimens incorporate nearly everything with the exception of the living tissues of higher plants. Presently with the revelation of the eating regimen of the Himalusa thailandensis, they are referred to expend that too. A couple of beetle species, remarkably those of the sort Aleochara, are foragers and flesh feeders, or are parasitoids of different bugs, especially of certain fly pupae. Most wander creepy crawlies are predators of bugs and different spineless creatures, living in woodland leaf litter and comparable rotting plant matter. They are likewise generally found under stones, and around freshwater edges. Different species have adjusted to living as inquilines in subterranean insect and termite settlements, and some live in mutualistic associations with warm-blooded animals whereby they eat bugs and different parasites, profiting the host.

The rove beetle’s appetite for the other insects makes them a good insect for pest control. However, any experiment with the wild insects have failed, and there has been a rather better success with the parasitoid species like the genus Aleochara. The Stenus genus of the rove beetle is among the most interesting species in the family of beetles. They have the ability to shoot out their labium from their head with the blood pressure. The labium is like a thin rod, and it ends with a pad of hooks and hairs. Between these hairs are pores that secrete a glue-like substance that captures their prey, and then they consume on these prey.

Rove Beetles’ Systematics

As of 2018, there are about 63,650 staphylinid species that are spread across ten families. These are further categorized into 32 subfamilies and 167 tribes. The various tribes are further broken down into 3,200 genera. More than 400 species of the rove beetle are discovered each year, and their population is growing each year. There controversies that about three-fourths of the species of the rove beetles are yet to be described.

How can the Rove Beetles Affect Human?

When you wonder as to do rove beetles bite, you should know that rove beetles don’t bite and neither do they sting. They, however, have a lot of secretions in their body, and that is what causes skin irritation and eye irritation in the human body. They have a chemical called the pederin in their blood, and this is a toxin for the humans. This toxin is much more potent for the humans than cobra venom as well. This is like a defense mechanism for the beetles, and their toxin is in their blood, and when you crush them, this chemical will get to your skin. Then you will have irritation, and it will cause blisters. You don’t have to worry as to do rove beetles bite make sure that you don’t crush their body with exposed skin. You will have a skin condition called the dermatitis linearis, and it is pretty painful and ugly to look at. You will have inflammation in the affected area, and there will be blisters around the exposed areas. The beetle can crush of if you swat them like a mosquito or if it hits you at high speeds. You may even get conjunctivitis or skin irritations like rashes as well.

The basic symptoms are the redness of the skin and then start the irritation and the itching. You will also have a burning feeling when they bite you. This is because of the poison in their blood. There will also be a lot of pain, and that is followed by extensive blistering and pustules on the skin in about three to four days. The pain and irritation last for about ten days, and after that time it gradually starts going off. In case there is no improvement in the skin conditions then you should refer to a doctor.

First Aid Tips: you should avoid exposure to the toxin of the beetle and also avoid the ingestion of the 9insect even by mistake. There is no specific first aid to this condition. When affected you should immediately wash the area with soapy and slightly warm water well. After that, you should compress the place with a cold object. This prevents the toxin from entering your skin pores, and you can also avail antihistamines. You should make sure that the toxin doesn’t penetrate through your skin. Washing immediately will remove most of the toxins before it has any time to affect your skin in any adverse ways. Applying aloe vera gel is also a good idea that will alleviate the various symptoms of the exposure to the venom. You should seek medications and consult a doctor if the symptoms of the skin irritation are extremely extensive.

Overall you should avoid any form of contact with the rove beetles. Even if they are on your skin, you should blow them away. If your place has a lot of these beetles around then, you should rather wear long-sleeved clothing and also full-length pants. You should also use insect screens while sleeping as well to keep the rove beetles away from you while sleeping. This is important because you don’t have a lot of control over your body while you are sleeping and you are not really well-aware while you are sleeping. Keep soapy water nearby in case you require them for first aid, and this is one of the best and almost like the only first aid for the toxins of the rove beetles.

Are Rove Beetles Good or Bad?

Are Rove Beetles Good or Bad

These beetles feed on smaller insects, and thus they can be a useful help in pest control. They also eat off the rotting tissues of the plants and this helps the plant for healing rather than rotting even further. They are beneficial in a number of other ways as well. One of the subfamilies of the rove beetles feeds on the root maggots, and this is another good aspect of the rove beetles. They prevent any form of harm caused to the roots of the plants by the root maggots. They are even growing in certain parts of Europe and Canada to save some crops as they are an alternative form of pest control. There are a lot of rove beetles in Florida already, and this is beneficial for the state.

There is no specific way to get them removed from a place. A few pesticides are there that can rid them away, but it is of no good. They cause no harm to the gardens. They feed on the other insects as well as the rotting plant tissues, and when there are no more of them in your garden, then they will go away from your garden on their own. They come and help you have a better and healthier garden for free and then leave you on your own when they are done with the rotting plants and the other smaller insects in your place.

The rove beetles are a subspecies of the beetles’ family and have many benefits to the humans. They are however poisonous for the human skin, and you should avoid any form of contact with them, and if done you should wash it off with soapy water.
