Caterpillars are also affected by a range of bacterial, viral and fungal diseases, and only a small percentage of the butterfly eggs laid ever reach adulthood. [79] The bacterium Bacillus thuringiensis has been used in sprays to reduce damage to crops by the caterpillars of the large white butterfly, and the entomopathogenic fungus Beauveria ...
Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of ...
The earliest known butterfly fossils are from the mid Eocene epoch, between 40-50 million years ago. [ 1 ] [ dubious – discuss ] Their development is closely linked to the evolution of flowering plants, since both adult butterflies and caterpillars feed on flowering plants.
It wasn't long ago that Caterpillar (NYS: CAT) , the world's biggest manufacturer of equipment used in heavy construction and other related tasks, was being rocked by the wobbly global economy.

The key characteristics that differentiate the Papilionidae from the other butterfly families are: [1] The osmeterium is a forked, fleshy eversible organ found in the prothoracic segment of caterpillars. Venation – in swallowtails, the second anal vein, 2A, extends up to the wing margin and does not link with the first anal vein, 1A. These ...
That the avian predators avoided the queen butterfly implies that the queen does not serve as a model and the viceroy as a parasitic mimic; rather, they may be Müllerian co-mimics. [18] When avian predators were exposed to butterfly abdomina without the wings, many avian predators rejected the viceroy after a single peck.
