Sesamia inferens, the Asiatic pink stem borer, gramineous stem borer, pink borer, pink rice borer, pink rice stem borer, pink stem borer, purple borer, purple stem borer or purplish stem borer, is a moth of the family Noctuidae. The species was first described by Francis Walker in 1856. [1]
The hindwings are whitish and semitransparent, and the wingspan of adult moths varies by age and sex. The average wingspan is 27–40 mm for females, and 23–32 mm for males. [6] The larvae of C. cactorum are caterpillars that start out with a pink-cream color and gradually become orange, with distinctive black spots or bands. [6]
Basic moth identification features. While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and ...
Female moths can attain a wingspan of 24 cm. The dorsal surfaces of their wings are mottled brown with hints of iridescent purple and pink, and, in females, crossed by a white bar. The diagnostic marking is a small spot on each forewing shaped like a number nine or a comma. This spot is often green with orange highlights.
The moths have lived in Europe and Asia for thousands of years but were accidentally introduced to Boston in the 1860s. Spongy moths feed on foliage of many plant varieties but prefer oak trees.
According to a traditional color scheme, which is of unknown origin, baby boys are properly dressed in pink clothing and baby girls in blue, although in some parts of the country, particularly in the Southern States, this symbolical color arrangement is reversed and baby boys are dressed in blue and girls in pink.
Hawk moths, including H. lineata, are considered long-tongued nectar foragers, although nearly 20% of all hawk moth species have very short tongues compared to H. lineata. A 1997 study found correlations between tongue length and latitude distribution: mean tongue length declines from around 40 mm to as short as 15 mm as northern latitude ...
Moths from the highlands, 900–1,080 metres (2,950–3,540 ft), have a median wingspan of 7 cm (2.8 in); moths from lower altitudes, 600 m (2,000 ft), have a median wingspan of 9 cm (3.5 in). [16] Like many other uraniine moths , the sunset moth has an uncanny resemblance to swallowtail butterflies , especially in its tails and colourful wings ...
