However, this sound could also be produced by the friction of the spines of the hind legs against the long hairs of the abdomen (CP pers. obs., and Weinmman pers. comm.). This behavioral display

seems.to respond to the same aposematic behavior described above for T. blondi, because the spider also sheds urticating setae while stridulating. Some species of Brachypelma also produce a sound similar to rubbing C. Ecological Importance of Urticating Hairs and Spines The lack of reproducible experiments on the correlation between feeding habits of insectfeeding vertebrates (amphibians, reptiles, birds, mammals) and equipment of caterpillars with urticating hairs and spines allows no final interpretation of their ecological importance. Generally they are believed to be defense mechanisms. Several observers report that hairy caterpillars, especially forms with urticating hairs, are not eaten by all Type I urticating bristles

from.Brachypelma emilia. These are the type that cause most of the itching in humans. (Artificially colorized.) Type Ill urticating bristles from Brachypelma emilia. While these urticating bristles are more picturesque than the type I, they're relatively benign to humans. (Artificially colorized.) from specimen bottles holding tarantulas is splashed on unprotected skin. It is not clear if the urticating properties of these bristles are caused by a chemical or a physical meridionalis x viburni, but this does not alter the general result, viz., that the larvae derived from four full batches of eggs, with $ meridionalis X ? viburni parentage, divided, as just noted, into two approximately equal portions, one with redbrown, the other

with.white, urticating fur, with no intermediates. The larvae of the second generation, i.e., larvae obtained from eggs laid by imagines produced from this cross, resulted as follows : Pairing between moths from larvae of whitehaired discovered and all later observers have also found on the cnidoblasts is nothing but a pedicle which stands in direct connexion with the supporting lamella and represents a product of metamorphosis of a part of the plasma of that cell which also produced the urticating capsule in its interior. He states that this pedicle possesses the same optical and chemical properties as the supporting lamella. From his careful observations, extended over all groups of the Coelenterata, he draws the (50) Hairs on

metatarsi.and tibiae 11V of males: (O) normal, (1) long hairs laterally projected, forming a brush. (51) Urticating hairs of males and females: (O) only nonurticating hairs present on the abdomen and pedipalps, (1) urticating hairs on dorsum of abdomen, (2) urticating hairs on distal prolateral face of pedipalps. (52) Type 1 urticating hairs in males and females: (O) absent, (1) present. (55) Type 11 urticating hairs in males and females: (O) absent, (1) present. (54) Type 111 To this instance are referred those species whose larvae, during specific developmental stages, bear urticating hairs, i.e. tegumentary appendages, connected to special glands, capable of eliciting adverse reactions in humans rangin from dermatitis and

conjunctivitis.to IgE mediated anaphylactic reactions (Wirtz, 1984', Arlian, 2002). In this chapter recent advance on these issues are discussed, with particular attention to environmentfriendly methods based on biological control
