Bald-faced hornet is constructed too close to human habitation. They vigorously defend the nest, with workers stinging repeatedly, as is common among social bees and wasps. However, the baldfaced hornet has a unique defense in that it can squirt or spray venom from the stinger into the eyes of vertebrate nest intruders. The venom causes immediate watering of the eyes and temporary blindness. The life cycle of a colony can be divided into the founding stage, the ergonomic stage and the reproductive stage. Colonies show annual cycling. New nests are generally founded during spring and early summer by a single queen, though
Insect diuretic hormones The complex is only present in lepidopteran larvae and some beetle species. Little is known about the hormonal control of fluid uptake by the cryptonephric complex, which is certain to play an important role in the species in which it occurs. First three letters of genus added to first two letters of the species name. For example, a 37-residue diuretic peptide from Tenebrio molitor will be named Tenmo-DH37. Insect diuretic hormones Insect diuretic hormones are hormones that regulate water balance through diuretic action. The insect excretory system, responsible for regulating water balance in the insect, comprises the Malpighian tubules and
