Weeders do not want to select weeds and their seeds that look increasingly like cultivated plants, yet there is no other option. For example, early barnyard grass, Echinochloa oryzoides , is a weed in rice fields and looks similar to rice; its seeds are often mixed in rice and have become difficult to separate through Vavilovian mimicry.

Additional plants which will provide for the needs of caterpillars and butterflies are: shasta daisy, black-eyed Susan, cardinal flower, phlox, cosmos, sedums, ironweed, mountain laurel, verbena ...
The frenulum can be observed only when a specimen is in hand. There is only one known species of butterfly with a frenulum, which is the male regent skipper Euschemon rafflesia. [5] Some moths have a lobe on the forewing called a jugum that helps in coupling with the hindwing. Butterflies lack these structures.
Some species in the Satyrinae use ferns as larval host plants, and it is not impossible that the butterflies could have originated before their present-day angiosperm plant hosts. Evidence from the historical diversification of fifteen butterfly groups that show an increase in the diversification rates that follow major host shifts. [3]
The model is an approximation, and assumes the species are equally unprofitable. Later models are more complex. If one is more distasteful than the other, then the relative gains differ further, the less distasteful species benefiting more (as a square of the relative distastefulness) from the protection afforded by mimicry.

Lepidoptera (/ ˌ l ɛ p ɪ ˈ d ɒ p t ər ə / LEP-ih-DOP-tər-ə) or lepidopterans is an order of winged insects which includes butterflies and moths.About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, [1] [2] making it the second largest insect order (behind Coleoptera) with 126 families [3] and 46 superfamilies ...
