Hycleus phaleratus, is a species of blister beetle found in China, Taiwan, Thailand, Indonesia, Nepal, India, Sri Lanka, and Pakistan. [1] It is sometimes considered a problem in agricultural cultivation but has been used in traditional Chinese medicine. [2] The species was formerly placed in the genus Mylabris .

Description

Body length is about 18 to 25.1 mm. Head with moderately coarse deep and dense punctures. Eyes longer and reniform. Maxillary palpi with triangular apical segment. Pronotum strongly convergent from apical third to apex. Pubescence long, and dense on pronotum. Elytra with moderately coarse, shallow punctures and short pubescence. Basal region consists with two yellowish spots. These spots become rectangular in shape from dorsally and laterally. The median and apical yellow bands are less undulate. Ventrum moderately and coarsely punctate and shiny. Male has shallowly emarginate sixth visible abdominal sternum, whereas female with entire apex in sixth visible abdominal sternum. [3] Elytral axillary spot convered with black setae. Fore margins of the mesepisterna almost parallel which runs along the median groove. In male, proximal aedeagal hook is closer to the distal one. [4]

In China, the beetle is important commercially in Chinese medicine, due to the ability to biosynthesize potent defensive blistering agent cantharidin. [5] [6] The beetle was traditionally used to treat tumors, carbuncle, scrofula, poor blood circulation, pleurisy, dropsy, pericarditis, and missed menstrual periods. [7] [8] Some side effects of the crude medicine obtained from H, phaleratus can cause abdominal pain and hemorrhagic shock. [9] [10]

Adults and grubs are pests on variety of agricultural crops and ornamentals such as: luffa, cowpea, Canna indica , rose, Gossypium hirsutum , green gram, okra, soy bean, tobacco and paddy. [11]

<span class="mw-page-title-main">Cantharidin</span> Chemical compound

Cantharidin is an odorless, colorless fatty substance of the terpenoid class, which is secreted by many species of blister beetles. It is a burn agent or a poison in large doses, but preparations containing it were historically used as aphrodisiacs. In its natural form, cantharidin is secreted by the male blister beetle, and given to the female as a copulatory gift during mating. Afterwards, the female beetle covers her eggs with it as a defense against predators.

<span class="mw-page-title-main">Blister beetle</span> Family of beetles

Blister beetles are beetles of the family Meloidae, so called for their defensive secretion of a blistering agent, cantharidin. About 7,500 species are known worldwide. Many are conspicuous and some are aposematically colored, announcing their toxicity to would-be predators.

<i>Hycleus</i> Genus of beetles

Hycleus is a genus of blister beetle belonging to the Meloidae family found in Africa and Asia. The genus contains over 400 species, which historically have been confused with the genus Mylabris.

<i>Ceroctis capensis</i> Species of beetle

Ceroctis capensis, or spotted blister beetle, is diurnal and endemic to Southern Africa occurring in diverse habitats, and belonging to the Meloidae or Blister beetle family. It secretes a toxic liquid from its leg joints when roughly handled, blistering human skin. This species somewhat resembles Mylabris oculata, a member of the same family.
