The scarlet lily beetle, or Lilioceris lilii, is commonly known as the lily leaf beetle or LLB. This is an invasive bug that originated in Eurasia. Lily leaf beetles feed on lily leaves, stems, buds and flowers. The bug reached North America during World War II on plants imported from Europe. LLB expanded into New England in the 1990s and then moved west.

The scarlet lily beetle can wreak havoc on native and farmed true lilies as well as fritillaria. LLB can also harm lilies of the valley and Solomon seals. LLB will not harm daylilies, canna lilies, or calla lilies.

Adult scarlet lily beetles emerge in early spring to feed, mate and lay eggs. Lily leaf beetles can spread over large areas in search of host plants. Females eventually lay 250-450 eggs.

The red-headed cardinal beetle, or Pyrochroa serraticornis, is similar to the lily beetle but has a more rounded body and sunken wing shells. The red-headed cardinal beetle has black legs and long, toothed antennae. The lily beetle arrived in the UK in the 1900s via imported flowers.

Red-headed cardinals inhabit woodlands, hedgerows, parks and gardens. In summer, adults can be seen basking on flowers or tree trunks. They are predators, feeding on insects that fly around the flowers they inhabit. Flat larvae can live under loose bark and feed on the larvae of other insects.

8. Common Red Beetle

The common red sailor beetle, or Rhagonycha fulva, is a summer-loving beetle attracted to open-structured flowers such as daisies, cow parsley, and hogweed. It inhabits grasslands, hedgerows, woodlands, parks and gardens. Adults devour aphids, pollen and nectar. The larvae feed on ground-dwelling invertebrates such as slugs and snails. A pair of adults mates for most of their short summer lives.

Adults eat aphids and larvae eat other pests. The common red navy beetle has long antennae and a thin body. It is orange-red in color with black markings on the wing casings.

7. Red Flour Beetle

The pink beetle is of Indo-Australian origin and lives in temperate climates. It exists in the southern states of the United States. The red flour beetle has been known to infest grain or dry stored food, especially grain products such as flour, cake mix, cornmeal, biscuits and dry pet food. Infected food contains adults and tiny off-white larvae. Adult beetles can be found in cupboards or anywhere in the house away from contaminated materials. Despite their small size (1/8 inch long), juveniles can live for three years or more.

Due to their similar appearance, biochemistry, and behavior, these beetles are often confused with the "confused" flour beetle. The confused flour beetle is named for its ambiguous identity. The red flour beetle has curved sides, while the fuzzy flour beetle has a straight chest. Both species have a global distribution. Both of these bugs also consume pantry items.

6. Fire Beetle

The fire-colored beetle, or Pedilus lugubris , has bright red wings and head that make it look dangerous, but it's not. Large, round black eyes are located on the sides of the head, and the antennae are dark red. Despite its beauty, this fire-colored beetle poses little threat to humans. It won't sting or spray caustic chemicals or bite. Their larvae have been known to hide behind rocks and in wood piles. After building firewood, adults can enter the room.

5. Fireflies

Fireflies are known as "cotton dyes" because they dye cotton plants red.

Firefly or Pyrrhocoris apterus is a common insect in the Pyrrhocoridae family. Its bright red and black colors may be confused with the unrelated Corizus hyoscyami , or cinnamon bug.

The firefly, a major cotton pest in North America and India, is often referred to as the "cotton dyer" because it damages cotton plants by sucking sap and droppings, coloring the bolls in the process.

Their diet includes limes and mallow seeds. They usually appear in clusters on the sunny side of the trunk of the linden tree. The bugs are oval and dark red and 8-18 mm (0.3 to 0.7 inches) long.

4. Red Velvet Ant

Red velvet ants are actually wasps.


The red velvet ant, or Dasymutilla occidentalis (Linnaeus), is actually a wasp, not an ant. Females are wingless and covered in fur like ants, while males have wings and can fly. They have many orange-red fur spots on their chest and belly. It is most common in adults in summer. Red velvet ants are about three-quarters of an inch long.

Female velvet ants have a powerful sting that has earned them the nickname "cow killers," although their sting is not strong enough to kill a cow. The "cow killer" nickname comes from the fact that the sting of the female velvet ant is particularly severe. Male red velvet ants have wings but no stingers.

3. Fire ants

Animal Information: Worker Ants
Fire ants are invasive and originated in South America


The fire ant, or Solenopsis saevissima , was mistakenly brought to North America from South America. Ants that are red or yellowish are 1-5 mm (up to about a quarter inch) long and have a sting. These "labourers" are known to destroy grain and injure chickens, and are notorious for being aggressive when threatened by neighboring ant colonies, young fire ants.

When provoked, fire ants can become aggressive and sting repeatedly. When stung, people may develop irritation and white, fluid-filled pustules. Sensitive individuals may experience swelling, chest pain, difficulty breathing, nausea and sweating. If this happens, seek medical attention immediately.

2. Red-banded Leafhopper

The red-banded leafhopper, or Graphocephala coccinea , is also known as the candy-striped leafhopper. It has bright red and blue stripes on its wings and chest, hence its name. Its head, legs and lower body are yellow in color. Leafhoppers are three-eighths of an inch long. They live in woods and grasslands and feed on the sap of leaves and stems.

Red-banded leafhoppers feed on ornamental plants such as Scotch gorse and crape myrtle. When this leafhopper pierces and sucks plant juices, it injects saliva. It can infect oaks, elms, sycamores, and other trees with Pierce's disease. Pierce's disease is a deadly grapevine infection. The bacterium Xylella fastidiosa causes it, and leafhoppers that feed on xylem bacteria spread it.

1. Black-and-Red-Bug ( Lygaeus equestris )

Horse carp


In the Lygaeidae family, Lygaeus equestris is a ground insect with the common name Black-and-Red-bug. These bugs are ½ inch long. Their wings are bright red and their legs are very long. The red and black pattern deters insects and protects them. Warm weather is crucial for L. equestris, a sun-loving insect.

The insect has been recorded feeding on a variety of plants. Many of them are poisonous. By accumulating toxic elements of the plants they feed on, they resent potential predators.
