Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
The adult moth has a wingspan up to 3 centimetres (1.2 in). The male has translucent wings, and the female is drab brown and gray, with yellow scales on her legs. The day-flying female is said to mimic a bee , complete with pollen sacs, and the male mimics a wasp .
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies.Their scientific name derives from the Ancient Greek geo γεω (derivative form of γῆ or γαῖα "the earth"), and metron μέτρον "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion.

During mating, the female stands still and holds her head to the side, looking up to see the opened mouth of the male. The red tongue apparently serves a signalling function. The female moves her head from left to right in the same rhythm as the male's cries. Afterwards, the female seeks out an adequate location to lay her eggs.
Moth antennae are either filiform (thread like), unipectinate (comb like), bipectinate (feather like), hooked, clubbed, or thickened. [13]: 636 Bombyx mandarina is an example with bipectinate antennae. [17] Some moths have knobbed antennae akin to those of butterflies, such as the family Castniidae. [18]

Luna moth females mate with the first males to find them, a process that typically starts after midnight and takes several hours. [2] Researchers extracted three chemical compounds from the pheromone gland of unmated Luna moth females and identified one major and two minor aldehyde compounds designated E 6, Z 11-18:Ald, E 6-18:Ald and Z 11-18:Ald.
