}} Halysidota tessellaris, also called the banded tussock moth, tessellated halisidota, and pale tiger moth, is in the family Erebidae. Like many related species, it has chemical defenses it acquires from its host plants, in this case, alkaloids (Weller et al., 1999, Hristov and Conner 2005), at least in adults. Larval brazen behaviours suggest that they are chemically protected; they have not been analyzed for alkaloid content. RangeThis moth is found from southern Canada south through Texas and central Florida in North America (Wagner 2005). Life cycleOne generation per year occurs in the north, and two or more occur in the south (Wagner 2005). EggEggs are laid in masses on the undersides of leaves (Rose and Lindquist, 1982). LarvaCaterpillars are covered with long setae, in tufts. They vary from yellowish and orange through dark gray. Extra long 'hair pencils' of white, black, and/or orange occur at both the front and rear of a caterpillar. Larval head capsules are bright orange. In the north, mature caterpillars are found from July to frost (Wagner 2005). Caterpillars frequently rest on the upper surface of leaves, and though not gregarious, they are very conspicuous (Wagner 2005). They grow to a length of 35 mm. PupaPupae overwinter in gray cocoons laced with larval hairs (Wagner, 2005). AdultsWings are light brown. Forewings have bands of beige edged in black. The body is 'hairy' and yellow. The thorax has blue-green lines on its upper sides. Adults are attracted to decaying plants with pyrrolizidine alkaloids (Krasnof and Dussourd, 1989). They regurgitate on them, then drink the fluids, and acquire defensive chemicals. Food plantsLarvae are known to feed on some species of alder, ash, birch, blueberry, chestnut, elm, grape, hackberry, hazel, oak, walnut, willow, and many others (Wagner, 2005). No serious injury to trees has been reported for this late-season feeder (Rose and Lindquist, 1982).
