19 Types of Beetles in Florida (And How to Identify Each One)
October 14, 2026
Florida hosts more than 200 documented beetle species, according to the InsectIdentification.org database, making Coleoptera one of the state’s most varied insect orders. From tiny pantry pests to a six-inch palm-boring weevil, these beetles fill nearly every ecological niche the state has to offer, recycling dung, pollinating flowers, boring into dead wood, and defending themselves with chemical warfare.
This guide walks through 19 types of beetles in Florida you are likely to encounter in a backyard, a pine flatwood, or even inside a pantry cupboard. Each entry covers what the beetle looks like, where it lives, and how to tell it apart from similar species. For a broader look at the insects sharing these habitats, see this overview of different types of insects found across North America.
Pro Tip: Most Florida beetles are harmless or even beneficial. Before reaching for pesticide, check whether the species you found is a predator, pollinator, or decomposer doing useful work in your yard.

1. Dung Beetle
Florida’s dung beetle fauna includes a mix of natives and intentionally introduced species that keep pastures clean. One of the showiest natives is the rainbow scarab, Phanaeus vindex, a stocky beetle found in Florida and across the eastern and central United States that carries a metallic horn on its head. Adults measure roughly 11 to 22 millimeters in length and are relatively bulky and oblong in shape.
Research on north-central Florida cattle farms found that native and exotic dung beetles coexist in large numbers, with one study collecting 39 species from 20 genera totaling over 62,000 beetles in pitfall traps over a multi-year survey. Four of the six most abundant species in that study turned out to be exotics, a reminder that Florida’s agricultural history shaped which beetles now dominate its pastures.
2. Large Rove Beetle
Rove beetles look unfinished at first glance: their elytra cover only the front portion of the abdomen, leaving several segments exposed. The large rove beetle, often identified in Florida records as Platydracus cinnamopterus, is a fast-moving predator that hunts fly larvae and other small invertebrates in leaf litter and compost piles.
When disturbed, these beetles raise their exposed abdomen in a scorpion-like threat display, though they have no sting. Gardeners in Florida and insects found across New York alike tend to overlook rove beetles simply because they move so quickly through mulch and debris.
3. Round-Necked Long-Horned Beetle
The roundnecked longhorn beetle, Parandra polita, stands apart from typical longhorns because its antennae are noticeably short for the family and its neck region is rounded rather than constricted. This dark, cylindrical beetle bores into decaying hardwood and old fence posts throughout Florida’s warmer counties.
Unlike the flashier longhorns covered later in this guide, P. polita is rarely seen in daylight. Most sightings happen when someone splits old firewood or pulls apart a rotting stump, similar to longhorn activity reported among beetle species documented in Virginia.
4. Shining Leaf Chafer
Shining leaf chafers get their name from the glossy, almost polished sheen on their wing covers. Florida’s best-known example is the grapevine beetle, Pelidnota punctata, a tan-to-orange beetle with black spots along the elytra margins that feeds on wild and cultivated grape foliage.
Adults are active on summer evenings and are often drawn to porch lights. Their larvae develop in decaying wood and root systems, a life cycle pattern shared with several beetle species native to Missouri and much of the eastern United States.
5. Flower Longhorn Beetle
Flower longhorn beetles belong to the subfamily Lepturinae and spend their adult lives on blooms rather than wood, despite larvae developing in rotting logs. Florida species in the genus Strangalia and related genera show slender, wedge-shaped bodies that narrow sharply toward the rear.
These beetles are important, if underappreciated, pollinators. They visit composite flowers for pollen and nectar, often alongside bees, and their long legs let them cling to petals while feeding, a trait also seen in flower-visiting beetles documented among beetle species found in Minnesota.
6. Soldier Beetle
Soldier beetles earn their military nickname from the leathery, soft elytra that resemble old-fashioned uniform coats rather than the hardened shells of most beetles. The margined leatherwing, Chauliognathus marginatus, is common in Florida gardens, showing a yellow-orange body with a dark central patch on each wing cover.
Both adults and larvae are predators of soft-bodied insects like aphids, making soldier beetles a welcome sight near vegetable beds. Gardeners who also track beneficial insects in Ohio will recognize the same genus patrolling flower heads there each summer.
7. Blister Beetle
Blister beetles produce cantharidin, a chemical defense that causes painful blistering on skin contact and can poison livestock that accidentally eat the beetles in dried hay. Florida species in the genus Epicauta are typically elongated, soft-bodied beetles with a narrow “neck” region behind the head.
Important Note: Never crush a blister beetle with bare skin. If cantharidin contacts skin, wash the area promptly and avoid touching eyes. Livestock owners should inspect hay for beetle bodies before feeding, since cantharidin remains toxic even in dead, dried beetles.
Adult blister beetles feed on flowers and foliage, sometimes in large groups, while larvae are predators of grasshopper eggs underground. Related species appear on lists of beetles recorded in California, where the same cantharidin warning applies.
8. Ground Beetle
Ground beetles form one of the largest beetle families in North America, and Florida’s representatives range from tiny leaf-litter hunters to the large, shiny black Pasimachus species that patrol sandy soils at night. Most ground beetles share a flattened, fast-moving body built for chasing down prey.
These beetles are voracious predators of caterpillars, slugs, and other garden pests, making them one of the more beneficial insects a homeowner can find under a porch light. Their nocturnal hunting habits put them in the same guild as several spider species found in Florida that patrol the same leaf litter after dark.
9. Bark Beetle
Bark beetles are small, cylindrical weevils in the subfamily Scolytinae that tunnel between bark and wood, carving distinctive galleries as they feed. Florida’s pine forests host several species, including engraver beetles in the genus Ips, which create characteristic Y- or H-shaped egg galleries under the bark of stressed or dying pines.
Healthy trees generally resist bark beetle attack, but drought-stressed or storm-damaged pines are vulnerable to mass colonization. Comparable outbreak patterns have been documented among bark-boring insects in Texas, where drought stress similarly triggers beetle population spikes.
10. Ambrosia Beetle
Ambrosia beetles take their name from the fungal “ambrosia” gardens they cultivate inside tunnels bored into wood. The redbay ambrosia beetle, Xyleborus glabratus, is Florida’s most consequential species in this group because it introduced the laurel wilt fungus that has killed large numbers of native redbay and swamp bay trees across the state.
Unlike bark beetles, ambrosia beetles do not feed on wood tissue directly; instead, they farm symbiotic fungus along their tunnel walls and feed on the fungal growth. This fungus-farming strategy parallels relationships found among some wood-boring insects documented in the Amazon rainforest, where fungus cultivation also drives insect-tree dynamics.
11. Ant-Like Longhorn Beetle
This small longhorn beetle mimics ants closely enough to confuse casual observers and likely some predators too. Cyrtophorus verrucosus shows a reddish-brown and black banded pattern on a narrow body, with legs positioned to enhance the ant-like silhouette as it scurries across dead branches.
Adults are usually found on recently dead or dying hardwood limbs, where females lay eggs that develop into wood-boring larvae. The ant mimicry strategy mirrors defensive tactics used by several beetles living alongside native ant species in Florida, borrowing protection from a group most predators avoid.
12. Common Furniture Beetle
The common furniture beetle, Anobium punctatum, is a small, brown, cylindrical beetle best known for boring into structural and furniture-grade wood. It belongs to a group of wood-boring beetle species found across Florida and the broader United States that target sapwood and new-growth timber rather than old, hardened heartwood.
Infestations are often first noticed through small round exit holes and fine, powdery frass left behind as larvae tunnel through wood over months or years. Because damage happens out of sight, furniture beetle infestations in older homes can go unnoticed until structural wood begins to weaken.
13. Red Flour Beetle
The red flour beetle, Tribolium castaneum, is a reddish-brown pantry pest that infests stored grain, flour, cereal, and similar dry goods. Adults are flattened and only about an eighth of an inch long, small enough to slip through poorly sealed packaging.
This species thrives in warm, humid conditions typical of Florida kitchens and food storage facilities, reproducing quickly once established in a grain source. The same pantry-invading habits show up in stored-product pests reported among insect species found in Canada, since global grain trade has spread this beetle nearly everywhere humans store food.
14. Redlegged Ham Beetle
The redlegged ham beetle, Necrobia rufipes, is a small, metallic blue-green beetle with distinctive reddish legs that gives it its common name. True to its name, it infests cured and dried meat products, including ham, bacon, and dried fish, making it a recurring concern in Florida smokehouses and meat storage areas.
Unlike grain pests, this beetle targets protein-rich stored foods and can also be found around dried cheese and some dried fruits. Pest control resources covering common beetles found in Florida list it among the state’s recurring household pantry invaders alongside the red flour beetle.
15. Bombardier Beetle
Bombardier beetles in the genus Brachinus defend themselves with a genuinely explosive trick: they mix stored chemicals in an internal chamber to fire a hot, corrosive spray at attackers. According to the National Wildlife Federation, this defensive compound is discharged through an abdominal tip that can rotate to aim precisely at a threat.
Florida hosts a notable share of the nation’s bombardier beetle diversity; researchers tracking the genus note that Florida alone has 19 recorded species, ten of which occur statewide. A separate but similarly patterned beetle, the false bombardier beetle (Galerita bicolor), mimics the true bombardier’s orange-and-black coloring without the chemical firepower, a bluff that is found from New York to Florida and west to Texas.
Pro Tip: If you see an orange-and-black ground beetle under a log, resist picking it up. Even the harmless mimic looks convincing enough to startle most people, and true bombardiers can deliver a genuinely unpleasant chemical burst.
16. Bess Beetle
Bess beetles are large, shiny black beetles found in rotting logs, where they live in family groups and communicate through audible chirps produced by rubbing body segments together. Florida is home to a rare endemic species, the Archbold bess beetle (Odontotaenius floridanus), which is found only on the Lake Wales Ridge and carries a critically imperiled conservation status.
The more widespread horned passalus, a close relative found throughout the southeastern United States, performs the same ecological role of breaking down decaying wood in forests. Both species show the social behavior rare among beetles, with adults and larvae cohabiting the same log and even feeding larvae predigested wood, a trait shared with beetle species reported in Arizona’s beetle fauna.
17. Palm Weevil
Florida’s native palmetto weevil, Rhynchophorus cruentatus, is the largest weevil in the United States, with adults reaching over two inches in length and a long curved snout used for feeding and boring into palm crowns. Its reddish-orange and black coloring makes it one of the more striking beetles a Floridian might spot near a palm tree.
Palmetto weevils typically attack stressed, damaged, or dying palms rather than healthy ones, laying eggs in the crown where larvae then feed. Palm groves hosting this weevil often share habitat with other Florida wildlife, including several gecko species found in Florida that bask on the same trunks.
18. Flower Chafer
Flower chafers belong to the subfamily Cetoniinae and are known for flying with their elytra closed, using only a notch near the wing base to extend their hind wings. The Delta flower scarab, Trigonopeltastes delta, is a distinctive Florida species with a yellow triangle marking on its black thorax that gives the beetle its name.
Adults feed on flower pollen and nectar, often visiting the same blooms as bees and flower longhorns described earlier in this guide. Their bold daytime activity contrasts with many nocturnal beetles on this list and places them among the more commonly photographed beetle species recorded in Maryland and the broader Southeast.
19. Colorado Potato Beetle
Despite its name, the Colorado potato beetle, Leptinotarsa decemlineata, is a widespread agricultural pest found well beyond Colorado, including parts of Florida where nightshade crops are grown. Adults display ten black stripes running down a yellow-orange back, making identification straightforward once you know the pattern.
Both larvae and adults feed on potato, tomato, and eggplant foliage, and heavy infestations can defoliate young plants quickly if left unchecked. Home gardeners managing this pest often rely on handpicking and row covers rather than broad pesticide use, since the beetle has developed resistance to many chemical treatments over the decades.
Florida’s beetle diversity reflects the state’s mix of subtropical forests, sandy scrub, agricultural land, and coastal habitats, each supporting a different slice of the Coleoptera order. Whether you encounter a rainbow-horned dung beetle in a pasture or a chirping bess beetle inside a rotting log, each species plays a distinct role in the ecosystem it calls home. Learning to tell a harmless soldier beetle from a cantharidin-producing blister beetle, or a true bombardier from its mimic, turns a backyard beetle sighting into a small lesson in Florida natural history.
