The Capability of Some Butterflies as Carriers of Common Milkweed Pollen [PDF]
, 2017 The common milkweed, Asclepias syriaca L., is remarkably adapted for cross pollination by insects. Its pollen sacs (pollinia) are often found attached to the appendages of bees, wasps, butterflies, and other insects that visit milkweed for its nectar ...

Multiscale Modeling & Simulation, 2015 The paper introduces the butterfly factorization as a data-sparse approximation for the matrices that satisfy a complementary low-rank property. The factorization can be constructed efficiently if either fast algorithms for applying the matrix and its adjoint are available or the entries of the matrix can be sampled individually.

Garden varieties: how attractive are recommended garden plants to butterflies? [PDF]
, 2015 One way the public can engage in insect conservation is through wildlife gardening, including the growing of insect-friendly flowers as sources of nectar. However, plant varieties differ in the types of insects they attract.

Butterflies (Lepidoptera) on Hill Prairies of Allamakee County, Iowa: A Comparison of the Late 1980s With 2013 [PDF]
, 2018 In the late 1980s, several hundred butterflies were collected by John Nehnevaj from hill prairies and a fen in Allamakee County, Iowa. Nehnevaj’s collection included 69 species, 14 of which are currently listed in Iowa as species of greatest conservation

Butterflies from Information Metric [PDF]
, 2016 We study time evolution of distance between thermal states excited by local operators, with different external couplings. We find that growth of the distance implies growth of commutators of operators, signifying the local excitations are scrambled.

Evolution of the Hofstadter butterfly in a tunable optical lattice [PDF]
, 2015 Recent advances in realizing artificial gauge fields on optical lattices promise experimental detection of topologically non-trivial energy spectra. Self-similar fractal energy structures generally known as Hofstadter butterflies depend sensitively on ...

Molecular logic behind the three-way stochastic choices that expand butterfly colour vision. [PDF]
, 2016 Butterflies rely extensively on colour vision to adapt to the natural world. Most species express a broad range of colour-sensitive Rhodopsin proteins in three types of ommatidia (unit eyes), which are distributed stochastically across the retina.
