Top 20 Most Common Insects in Cuba

In this species the sexes may differ with the female being either light or dark colored.Larvae have distinct body segments within which there appears to be four to six subsegments. They are purplish-green with two longitudinal, greenish-yellow stripes on each side and the dorsal side. When full-grown, they are approximately 3 cm long.The wingspan in adults is 6 - 9 cm.

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.

The queen butterfly (Danaus gilippus) is a North and South American butterfly in the family Nymphalidae with a wingspan of 70–88 mm (2.8–3.5 in). It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It is found throughout the tropics and into the temperate regions of the Americas, Asia and Africa. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropic queen; Danaus eresimus); in any case, it is not close to the plain tiger (Danaus chrysippus) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar from flowers. Unpalatability to avian predators is a feature of the butterfly; however, its level is highly variable. Unpalatability is correlated with the level of cardenolides obtained via the larval diet, but other compounds like alkaloids also play a part in promoting distastefulness. Males patrol to search for females, who may mate up to 15 times a day. Male organs called hair-pencils play an important role in courtship, with males with lower hair-pencil levels being selected against. These hair-pencils may be involved in releasing pheromones during courtship that could attract female mates.

The length of the forewings is 1.4 - 1.9 cm for males and 1.7 - 2 cm for females.

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.

Found mostly only on the islands of the Caribbean, purple land crab (Gecarcinus ruricola) is notable as the crab species that you are most likely to see far away from the sea. It is often seen by beachcombers or everyday people; it will not hesitate to venture significant distances. However, this species is largely nocturnal to prevent the sun from drying out its shell.

The wingspan is 2 - 3.5 cm.

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.

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.

Erythrodiplax umbrata is a dragonfly species of the genus Erythrodiplax from the subfamily Sympetrinae. It occurs in Central and South America as well as in the South of North America. Their English trivial name is "band-winged dragonlet".
