Top 20 Most Common Insects in Nueva Ecija

Danaus melanippus, the black veined tiger, white tiger, common tiger, or eastern common tiger, is a butterfly species found in tropical Asia which belongs to the "crows and tigers", that is, the danaine group of the brush-footed butterflies family. It ranges from Assam in eastern India through South-East Asia south to Indonesia, and eastwards to the Philippines and through southern China to Taiwan. It has around 17 subspecies, and its closest relative is the Malay tiger, Danaus affinis.

The larva of the tobacco cutworm is a major pest of agricultural crops such as tobacco, cotton, soybeans, and cabbage. These larvae feed on leaves voraciously. When the moth emerges into the adult stage, 70% of their total matings occur on their second night as an adult.

Prosotas dubiosa is a butterfly from the Lycaenidae family. The scientific name of the species was first validly published in 1879 by Semper.

Daphnis nerii, the oleander hawk-moth or army green moth, is a moth of the family Sphingidae. It was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.

The wingspan is about 30 mm. Adults have translucent whitish wings with broad dark brown borders. The body is whitish below, and brown on top of head and thorax as well as the end of the abdomen. There is a tuft of light brown "hairs" on the tip of the abdomen, vestigial in the male but well developed in the female. It is formed by long scales which are carried in a pocket on each side of the 7th abdominal segment, from where they can be everted to form the tufts. Unfertilized females are often seen sitting around with the tuft fully spread, forming two flower-like clumps of scales, which move slowly to spread their pheromones. These have been identified as consisting mainly of (E,E)-10,12-hexadecadienal and (E)-11-hexadecenal. From its closest relatives, the cucumber moth is most reliably distinguished by microscopic examination of the genitals. In the male, the clasper's harpe is twice as long as it is wide, with the costa and sacculus running almost in parallel and being strongly sclerotized, and a rounded cucullus. From the center of the harpe, which is otherwise only weakly sclerotized, a thin spine extends. The uncus is covered in bristles and ends in a small tube; it is a bit longer than the tegumen which in turn is about as wide as it is long. The vinculum is almost quadratic, and the anellus forms a small triangular plate which is more strongly sclerotized. The aedeagus is almost straight, strongly sclerotized below, and has a flattened curved process at end. In the female genitals, the ostium is transverse and oval, and the antrum broadly sclerotized. The ductus seminalis insert from above, a bit before the forward edge of the antrum. The bursa copulatrix is long and slim, with the forward third particularly narrow; its wall is covered with many short spines, and the hind end almost seamlessly merges into a short and barely distinguishable ductus bursae.

The Senegal Pechlibelle (Ischnura senegalensis) is a dragonfly from the family of the slender dragonflies (Coenagrionidae).
