Many species have "hairy" caterpillars that are popularly known as woolly bears or woolly worms. The scientific name Arctiinae refers to this hairiness (Gk. αρκτος = a bear). Some species within the Arctiinae have the word "tussock"' in their common names because they have been misidentified as members of the Lymantriinae subfamily based ...
Lonomia obliqua is a species of saturniid moth ("giant silk moth") from South America. [1] It is famous for its larval form, rather than the adult moth, primarily because of the caterpillar's defense mechanism, urticating bristles that inject a potentially deadly venom.
The adult moth is covered in long fur in colors ranging from dull orange to lemon yellow, with hairy legs and fuzzy black feet. [ citation needed ] The cocoons that these caterpillars emerge from vary in size from 1.3 to 2.0 centimeters and contain small hair pockets on the back and flattened front end, the latter covering the operculum at ...
Stings from this toxic creature can cause headaches, nausea, vomiting, chest pain and blood spots around affected region. Despite their cute fuzzy exterior, stay away from these harmful caterpillars.
These toxic species, such as the cinnabar moth (Tyria jacobaeae) and monarch (Danaus plexippus) caterpillars, usually advertise themselves with the danger colors of red, yellow and black, often in bright stripes (see aposematism). Any predator that attempts to eat a caterpillar with an aggressive defense mechanism will learn and avoid future ...
Caterpillar (top view) The larva, a caterpillar, is completely covered in long, hairlike setae arranged in spreading tufts. Most are white, but there are black tufts along the middle of the back, and four long black hair pencils, two near the front, and two near the back. There are black spots along the sides, and the head capsule is black.
The larvae are distinctly hairy with rows of orange tufts of long hair along the sides of the body. Arranged at the head are three large coppery tufts and two smaller purple tufts. Along the dorsal side of the caterpillars is a row of black triangles flanked either side by white. [1] [3]
They are gregarious until their third instar. Later instars sport tufts of black, white and orange (sometimes yellow) setae (hairs). The head capsule is black. The later instars wander much more, and may appear alone or in groups of up to 10. Mature caterpillars occur from June onwards. [4] Larvae grow as long as 35 mm.
