coerulea flowers, two groups of moths were identified, one with patches of pollen near their eyes and ones with no detectable pollen on their bodies. lineata nectar feeding patterns in Emerald Lake, Colorado, specifically on Aquilegia coerulea flowers. As caterpillars they feed on a huge diversity of host plants and as adults they prefer nectar over flowers. lineata are common pollinators and are known to collect nectar from flowers. If they're diurnal, they will choose flowers that are more brightly colored. If the adults are nocturnal, they will choose flowers that are white or pale colored, which are easier to identify in contrast to the dark foliage surrounding the flower. The adults will feed on different flowers depending on its behavior and on whether they are diurnal or nocturnal. They have also been seen in abundance in the mountains of Colorado, but their presence varies from year to year in many places. lineata are known to live a variety of habitats, including deserts, gardens and suburbs. The abundance of Hyles lineata populations in specific locations varies significantly from year to year, and has been thought to influence selection on flower phenotypes, although studies throughout the years show mixed results. Populations have also been seen in Eurasia and Africa. They can also be found occasionally in the West Indies.
This range extends from Central America to southern Canada through Mexico and most of the United States. Hyles lineata is one of the most abundant hawk moths in North America and has a very wide geographic range. The larva can also sometimes be lime green and black. This horn, which may sometimes be yellow and have a black tip, is not a stinger, and the caterpillars are not harmful to humans. An orange horn protruding from the back of the body is a distinguishing characteristic of Hyles lineata caterpillars. Their head's prothoracic shield, and the anal plate, are one color, either green or orange with small black dots. The larvae are black with orange spots arranged in lines down the whole body.
