Arctiidae is a large and diverse family of moths with around 11,000 species found all over the world, with 6000 Neotropical species (Scoble 1995). Arthropods are Animals belonging to the Phylum Arthropoda (from Greek ἄρθρον arthron, " Joint " Insects ( Class Insecta) are a major group of Arthropods and the most diverse group of Animals on the Earth with over a million described Lepidoptera is an order of Insect that includes Moths and butterflies. Macrolepidoptera is a group within the Insect order Lepidoptera. Noctuoidea is the Superfamily of noctuid ( Latin "night owl" or "owlet" Moths and has the largest number of Species William Elford Leach FRS ( 2 February 1790 – 26 August 1836) was an English Zoologist and Marine biologist The large Moth family Arctiidae contains the following genera A B C D E F G H In biology a type is that which fixes a name to a Taxon.

This family includes the groups commonly known as tiger moths (or tigers), which usually have bright colours, footmen (which are usually much drabber), lichen moths and wasp moths. Many species have 'hairy' caterpillars which are popularly known as woolly bears or woolly worms. The scientific name refers to this (Gk. αρκτος = a bear). Caterpillars may also go by the name 'tussock moths' (more usually this refers to Lymantriidae, however). Lymantriidae or Liparidae is a family of Moths with about 350 known genera and over 2500 known Species found all over the world in every

Diagnosis

The most distinctive feature of the family is a tymbal organ on the metathorax (Scoble 1995). This organ has membranes which are vibrated to produce ultrasonic sounds. They also have thoracic tympanal organs for hearing, a trait which has a fairly broad distribution in the Lepidoptera but the location and structure is distinctive to the family. A Tympanal organ is a hearing organ in Insects, consisting of a membrane ( tympanum) stretched across a frame backed by an air sac Other distinctive traits are particular setae ('hairs') on the larvae, wing venation, and a pair of glands near the ovipositor (Scoble, 1995). The sounds are used in mating (Simmons and Conner 1996) and defense against predators (Fullard et al, 1994).

Aposematism

Many species retain distasteful or poisonous chemicals acquired from their host plants (Weller et al. , 1999). Some species also have the ability to make their own defenses (Nishida, 2002). Common defenses include: cardiac glycosides (or cardenolides), pyrrolizidine alkaloids, pyrazines and histamines (Weller et al. Cardiac glycosides are drugs used in the treatment of Congestive heart failure and cardiac Arrhythmia. Cardenolides are a type of Steroids. Many plants contain cardenolides in the form of cardenolide glycosides (i This article is about the chemical compounds alkaloids For the Pharmaceutical company in the Republic of Macedonia see Alkaloid (company. Pyrazine is a Heterocyclic Aromatic Organic compound. Pyrazine is a symmetrical molecule with Point group D2h Histamine is a Biogenic amine involved in local immune responses as well as regulating physiological function in the gut and acting as a Neurotransmitter , 1999). Larvae usually acquire these chemicals, and may retain them in the adult stage. But adults can acquire them too, by regurgitating on decomposing plants containing the compounds, and sucking up the fluid (Weller et al. , 1999). Adults can transfer the defenses to their eggs, and males sometimes transfer them to females to help with defense of the eggs. Larval 'hairs' may be stinging, due to histamines the caterpillar makes in some species, but not all.

The insects advertise these defenses with aposematic bright coloration, unusual postures, odours, or, in adults, ultrasonic vibrations. Some mimic moths that are poisonous, or wasps that sting (Simmons and Weller, 2002). Biological mimicry occurs when a group of organisms the mimics, have A wasp is any Insect of the order Hymenoptera and suborder Apocrita that is neither a Bee nor Ant. The ultrasound signals help nocturnal predators to learn to avoid the moths (Dunning and Roeder 1965, Hristov and Conner, 2005), and can interfere with the bat's ability to precisely locate flying moths (Ratcliffe and Fullard, 2005).

Life cycle

Many of the caterpillars and adults are active during the daytime. If disturbed, woolly bear caterpillars will roll into a tight spiral. Common folklore has it that the forthcoming severity of a winter can be predicted by the amount of black on the Isabella tiger moth's caterpillar, the most familiar woolly bear in North America; however the relative width of the black band varies among instars, not according to weather (Wagner 2005). Isabella tiger moths (Pyrrharctia isabella) overwinter in the caterpillar stage. The common moth Pyrrharctia isabella is known by different common names at its two main life stages They can survive freezing at moderate subzero temperatures by producing a cryo-protectant chemical (Layne and Kuharsky 2000). The larvae of another species, Phragmatobia fuliginosa may be found on snow seeking a place to pupate.

Although they may be abundant, few species in this family are of economic importance. Even the fall webworm, an abundant and highly polyphagous tree-feeding species that has spread from North America to Asia and Europe, does not do lasting damage to healthy hosts. Fall webworm, Hyphantria cunea, is a Moth in the family Arctiidae known principally for its larval stage where it creates the characteristic webbed

Lore

Local lore of the American Northeast holds that that "Wooly bears" have the ability to predict the weather, similar to that of the Groundhog. The United States of America —commonly referred to as the The groundhog ( Marmota monax) also known as the woodchuck land beaver or whistlepig, is a Rodent of the family Sciuridae The lore goes: "More brown than black means a fair winter, but more black than brown means there is going to be a harsh winter". While there is no truth to this theory (the offspring of a single female can range from almost completely brown to almost completely black), they possess mythical qualities in the American Northeast, leading to such things as the Woollybear Festival. The annual Woollybear Festival is held every Fall in downtown Vermilion Ohio, an outskirt city on Cleveland 's west side
