Top 20 Most Common Insects in Guayaquil

Abracris flavolineata is a right-winged insect from the family locusts (Acrididae). The scientific name of this species was first validly published in 1773 by De Geer.

The tersa sphinx (Xylophanes tersa) has stiff wings that make it resemble a small bird. The adults might seem intimidating because their abdomen comes to a sharp point, but they have no stinger and are harmless to humans. The larvae are typically a bright green color or brown color with eye-spots, much different than the dull brown color of the adults.

Amarynthis meneria was described by Cramer in 1776.

The species is found in Europe.

Marpesia chiron, the many-banded daggerwing, is a species of daggerwings, map butterflies in the family Nymphalidae. It is found in Central America, North America, and South America. The MONA or Hodges number for Marpesia chiron is 4549.

Caligo eurilochus, the forest giant owl, is an owl butterfly (tribe Brassolini of nymphalid subfamily Morphinae) ranging from Mexico, through Central America, to the Amazon River basin in South America. It is a very large butterfly, among the largest in its family, with a wingspan up to 17 centimetres. The type locality is Suriname. Several subspecies are recognized, but many more have been proposed. The larvae feed on several host plants, including Calathea latifolia (Marantaceae), Heychium sp. (Zingiberaceae), Heliconia latispatha (Heliconiaceae), and Musa spp. (Musaceae). The larva also feed on the fruit of most Musa species. The female lays a large number of eggs of one of the host plants and the small larvae hatch after about 3 to 5 days. Fertile eggs develop a grey ring just above the center. Infertile eggs collapse. The first instar of the larvae are white with two orange/brown stripes down the length of their body leading to two little spindles at the end. Later on in life the larvae develop hairs mimicking spines and a crown made of four horns at the back of their head. The larvae then find a high enough spot to pupate and begin the change of metamorphosis. The large owl butterfly emerges and begins to pump out its wings, later searching for food. the butterflies drink the juices of fermenting fruits and a wide variety of nectar plants.

The giant Crab Spider is a large spider native to the tropics; the largest reported individual had a leg span of 30 cm.

Erinnyis ello, the ello sphinx, is a moth of the family Sphingidae. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. It is distributed from Argentina through Central America to the United States as far north as Nevada. The wingspan is 75–85 mm. The abdomen has gray and black bands. The forewing upperside of the female is pale gray with a few dark dots near the outer margin, while the forewing upperside of the male is dark gray and brown with a black band running from the base to the tip. In both sexes, the hindwing upperside is orange with a wide black border. Adults are on wing year-round in the tropics and southern Florida. Adults feed on the nectar of flowers, including common soapwort (Saponaria officinalis) and Chinese violet (Asystasia gangetica). The larva feeds on a variety of host plants, including papaya (Carica papaya) in the family Caricaceae; poinsettia (Euphorbia pulcherrima), Mexican jumping bean (Sebastiania pavoniana), Cnidoscolus urens, and cassava (Manihot esculenta) in the Euphorbiaceae; guavas (Psidium spp.) in the Myrtaceae; and saffron plum (Sideroxylon celastrinum) in the Sapotaceae. The ello sphinx can be parasitized by the braconid wasp Microplitis figueresi.

The wingspan is 11 - 13 cm.
