Many members of the genus Passiflora have evolved to produce very tough, thick leaves that are hard to break down by caterpillars. Some Passiflora vines have gone further by producing small leaves that look like a perfect place for the butterflies to lay eggs but break off at the stem within a few days, carrying the D. iulia eggs with
Junonia coenia, known as the common buckeye or buckeye, is a butterfly in the family Nymphalidae.Its range covers much of North America and some of Central America, including most of the eastern half of the US, the lower to middle Midwest, the Southwest (including most of California), southern Canada, and Mexico.
Also on the wings are small and oval scaleless areas (hyaline spots) that look like transparent "windows" and mimic holes left by insect larvae on leaves. [ 12 ] [ 16 ] A 1902 illustration of two specimens of Kallima paralekta shows one with wings folded and almost indistinguishable from the dead leaves, and one with wings outstretched showing ...
Eastern giant swallowtail butterflies must correctly identify their host plants by antennal sensitivity to the specific volatile compounds in the plants. A study found that antennal response to these volatiles depends upon the concentration of the volatiles, the host plant of origin (whether it is a primary or secondary host), and the sex of ...
Perching males frequently fly towards other butterflies. [1] Each male perches on one to four trees daily, without difference between seasons, and each tree used has a minimum daily mean of 1.5 perching butterflies. Most interactions occur from 13:00 through 15:00 hours and are more frequent in the rainy season. At night males share perches. [1]
The elusive animals were discovered in Ecuador after extensive searching, researchers said.
The U.S. Fish and Wildlife Service is pushing for added protections for the monarch butterfly after suggesting multiple populations could go extinct in mere decades.
The caterpillars of the gray hairstreak butterfly consume a wide range of food plants. [3] However, they do mainly use mallows and legumes as their preferred host plant. They commonly use clovers as their food plant as well, eating rabbit-foot clover (Trifolium arvense), white clover (T. repens), bush clover (Lespedeza capitata), white sweet-clover (Melilotis alba), and Malva neglecta.
