The major color components in their respective chemical structures are carminic acid (in cochineal dyes), kermesic acid (in kermes dye) and laccaic acids (in lac dye). [22] Carminic acid is extracted from the female cochineal insects and is treated to produce carmine, which can yield shades of red such as crimson and scarlet. [23]
The insects produce carminic acid as an antipredator adaptation. It is processed to produce the pigment carmine, which has long been used as a red food coloring and a natural dye for textiles . Dactylopius coccus , the true cochineal, is the species most commonly used today and historically, because it has a higher carminic acid content and ...
Carmine (/ ˈ k ɑːr m ə n, ˈ k ɑːr m aɪ n /) – also called cochineal (when it is extracted from the cochineal insect), cochineal extract, crimson lake, or carmine lake – is a pigment of a bright-red color obtained from the aluminium complex derived from carminic acid. [2] Specific code names for the pigment include natural red 4, C.I ...

Pelidnota punctata, the grapevine beetle, spotted June beetle or spotted pelidnota, is a species of beetle in the family Scarabaeidae (Scarab beetles), subfamily Rutelinae. Grapevine beetles are common in the north and central United States and eastern Canada, but do relatively little damage to their host plants.
The vireos are a group of small to medium-sized passerine birds. They are typically greenish in color and resemble wood warblers apart from their heavier bills. Nine species have been recorded in Illinois. White-eyed vireo, Vireo griseus; Bell's vireo, Vireo bellii; Yellow-throated vireo, Vireo flavifrons; Cassin's vireo, Vireo cassinii (A)
Common names for this genus and many other related genera in the subfamily Melolonthinae are May beetles, June bugs, and July beetles. [ 1 ] [ 2 ] They range in size from 12 to 35 mm (0.47 to 1.38 in) [ 1 ] [ 2 ] and are blackish or reddish-brown in colour, without prominent markings, and often rather hairy ventrally.
Furthermore, Ips pini beetles possess the capability to act as vectors for a particular type of blue stain fungus, which plays a crucial role in the beetles' ability to kill their host trees. This process involves the fungus clogging the water transportation systems within the tree, effectively disrupting the tree's ability to transport water.
