Top 20 Most Common Insects in Dominican Republic
Insects, creatures with unique features, play fascinating roles in Dominican Republic's rich ecosystems - as both helpful allies and pesky adversaries. The country's diverse geography, varying from lush rainforests to arid deserts, encourages a distinctive diversity of insect life. In this review, we list the top 20 most common insects found across Dominican Republic, revealing how their existence is intricately tied to their environment.
Most Common Insects
1. Zebra longwing
The zebra longwing (Heliconius charithonia) is a beautiful butterfly that has a texture resembling a zebra. They feast and pollen and nectar, using the pollen to produce chemicals that poison predators if they are eaten, deterring most predators from attack. Unfortunately, their populations have been decimated after being caught in the crossfire of sprays meant to control mosquitos.
2. Western honey bee
Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.
3. White peacock
The wingspan of the moths is 51 to 70 millimeters. The basic color is whitish. On the forewings there is a black, circular spot near the inner angle. At the front edge, two to three oblong, yellow-brown spots stand out. The Submarginalregion is also yellow-brown colored and crossed by dark lines. On the hind wings are two more small, black, circular spots near the tawny and dark-colored submarginal region. A short tail is more or less strong. The wing underside shows similar drawing elements as the top, but these are paler and weaker pronounced.
4. Lime swallowtail
The lime swallowtail (Papilio demoleus) has a beautiful black and white pattern, but it's considered a major pest to citrus trees. It feeds on nearly any type of citrus, including oranges and limes. This butterfly's small, green larvae are capable of defoliating an entire nursery grove. They are truly trouble makers in the citrus orchard.
5. Malachite
Siproeta stelenes (malachite) is a Neotropical brush-footed butterfly (family Nymphalidae). The malachite has large wings that are black and brilliant green or yellow-green on the upperside and light brown and olive green on the underside. It is named for the mineral malachite, which is similar in color to the bright green on the butterfly's wings. Typically, the wingspread is between 8.5 and 10 cm (3.3 and 3.9 in). The malachite is found throughout Central and northern South America, where it is one of the most common butterfly species. Its distribution extends as far north as southern Texas and the tip of Florida, to Cuba as subspecies S. s. insularis (Holland, 1916), and S. s. biplagiata, and south to Brazil. Adults feed on flower nectar, rotting fruit, dead animals, and bat dung. Females lay eggs on the new leaves of plants in the family Acanthaceae, especially ruellia. The larvae are horned, spiny, black caterpillars with red markings, The pupa stage is green and have sharp, gold spines that can puncture predators. Malachites often are confused with Philaethria dido. They have similar coloration, but their wing shapes are different. 
6. Caribbean hermit crab
Caribbean hermit crab (Coenobita clypeatus) is a land hermit crab found in many parts of the western Atlantic and the Caribbean sea. This herbivorous and scavenging crab uses modified gills to breathe air. It prefers the shells of West Indian top snail (Cittarium pica). The caribbean hermit crab is one of the two species of hermit crabs found in the pet trade in the US.
7. Gray cracker
The wingspan is 7 - 9 cm. The upperside is mottled brown and white although there is some red in the forewing cell bar. The hindwing eyespots have orange scales preceding black crescents. The underside of the hindwings is white and the submarginal eyespots are composed of a brown ring around a black crescent in a white center.
8. Julia heliconian
The julia heliconian feeds on nectar, with the passionfruit vine being a common host plant. The males will suck fluid from mud and decomposing plant matter to gain essential minerals, and they sometimes irritate the eyes of caimans and turtles in order to suck the tears they produce.
9. Tetrio sphinx
The adult moth is brown with gray and white markings, and the hindwing is a darker brown. The female may be lighter in tone. The body has gray, white, and black bands. The wingspan is 13 - 14 cm, and the female is generally slightly larger than the male. The larva is a caterpillar which may exceed 15 cm in length. It is black with aposematic yellow bands and a red-orange head. Toward the posterior end is an orange bump with a black horn roughly 2 cm long. The legs are orange with black spots. The pupa is about 7 cm long. It is yellow when new, turning brown and darkening to a reddish brown as it hardens.
10. Yellowline arrow crab
The body of S. seticornis is triangular, and the rostrum is drawn out into a long point with serrate edges. The legs are also long and thin, up to 10 cm (3.9 in) across, and the animal's carapace may be up to 6 cm (2.4 in) long. Colouration is variable in this species; the body may be golden, yellow or cream, marked with brown, black or iridescent-blue lines; the legs are reddish or yellow, and the claws are blue or violet.
