Dot-Lined Angle

Fascinating facts about the Dot-Lined Angle

• The dot-lined angle moth spread across the Pacific faster than most insects, hopping from Hawaii in 1970 to Guam by 1985 and reaching New Caledonia just two years later. Its first recorded arrival on the Hawaiian islands was in 1970, and by 1984 it was documented on all the main islands. Subsequent introductions listed include Yap in 1975, the Bonin Islands in 1976, Saipan in 1977, Okinawa in 1980, Taiwan in 1983, and a cascade of islands through the mid-1980s, showing how quickly a small 22-27 mm moth can colonise distant habitats.
• Despite its tiny size, the dot-lined angle's wings are marked with a line of tiny dots that give the species its common name. The phrase "dot-lined" comes from the evidence of small dots along the postmedial and sometimes median line of both forewing and hindwing(anterior of the marginal band).
• Larvae of the dot-lined angle feed on a surprisingly wide range of plants, from native legumes to cultivated crops, showing the moth's adaptability to different habitats. Recorded host plants in its natural range include Vachellia farnesiana, Cassia, Sesbania, Parkinsonia aculeata and Glycine max. In Hawaii it has been seen on Acacia koa, introduced Lysiloma latisiliquum and Litchi chinensis, while in the Indo-Australian tropics it has been reared from Leucaena and Mimosa diplotricha.
• Within a decade the dot-lined angle leapt from a single Hawaiian release in 1970 to a pan-Pacific presence, appearing on Yap by 1975, the Bonin Islands in 1976, Saipan in 1977, Okinawa in 1980, Taiwan in 1983, Guam by 1985, Sulawesi in 1986, and continuing onto Tonga, Fiji, the Philippines, New Caledonia, Malaysia, Samoa and Hong Kong through the late-1980s and early-1990s. This cascade shows how a modest moth can hitch rides on trade and travel, turning isolated islands into stepping-stones for invasive spread, threatening native insects and plants across the region.
• Native from northern Argentina through the Caribbean up to the southern United States, the dot-lined angle now drifts far beyond its original borders, regularly wandering north to Colorado, Kentucky and other more northern states.

About the Dot-Lined Angle

In the dappled light of the forest floor, the Dot-Lined Angle moth dances with delicate precision, its subtle, mottled wings beating in a hypnotic rhythm as it navigates the intricate tapestry of leaf litter and twisted roots. With each delicate flutter, the moth weaves a winding path through the underbrush, its pale, speckled form blending seamlessly into the surrounding shadows, a master of stealth and concealment. As it moves, the moth's slender body seems to embody the very essence of the forest, a fleeting, ethereal presence that whispers secrets to the trees.
