Simple SummaryButterfly larvae and adults can sense food odours from their surroundings, and exposure to these odours could alter larval or adult feeding preferences. However, it is still unknown whether butterfly pupae can sense odours from their surroundings. And little is known about how flower scents, in combination with food, affect butterfly adults’ subsequent foraging behaviour.Tirumala limniace(Lepidoptera: Danaidae) is a flower-visiting and highly charismatic butterfly. In this study,T. limniacepupae were exposed to the odour α-pinene and adults were exposed to the odours α-pinene and ethyl acetate to examine the effect of the experience on the foraging behaviour ofT. limniace. The results showed that exposure ofT. limniacepupae to α-pinene affected the feeding preference of newly emerged adults.T. limniaceexhibits olfactory learning in the adult stage, and adult odour preferences are correlated with the frequency of their training, though an increased training time does not necessarily imply an enhanced learning ability. Unlike some studies in other systems, we found thatT. limniacemales learned odours faster than females. This may be due to differences in antennal sensilla, affecting sensitivity to odours and nectar demand between males and females. Our study can help elucidate the important role of learning behaviour in butterfly adaptive responses to the environment and lay the foundation for further research on butterfly learning and memory.AbstractButterflies have the ability to learn to associate olfactory information with abundant food sources during foraging. How the co-occurrence of both food and food odours affects the learning behaviour of adults and whether butterflies perceive the odour of their surroundings and develop a preference for that odour during the pupal stage have rarely been tested. We examined the effect of experience with food odour components (α-pinene and ethyl acetate) during the pupal and adult stages on the foraging behaviour of the flower-visiting butterflyTirumala limniace. We found that α-pinene exposure during the pupal stage changed the foraging preference of newly emerged adults.T. limniaceexhibits olfactory learning in the adult stage, and adult learning may influence their previous pupal memory. Moreover, adults’ odour preference did not continue to increase over multiple training times. The learning ability of adults for floral odours (α-pinene) was greater than that for non-floral odours (ethyl acetate). In contrast to previous studies, we found that males learned odours more efficiently than females did. This could be attributed to differences in antennal sensilla, affecting sensitivity to compounds and nectar demand between males and females. Our study provides further insight into how olfactory learning helps flower-visiting butterflies use food odours to forage better.

The organic ligand (1-methyl-1H-benzo[d]imidazol-2-yl)methanol (HL) was used to react with CoX2·6H2O (X = Cl and Br) under solvothermal conditions to obtain the complex [Co4(L)6(X)2] (1, X = Cl; 2, X = Br). The butterfly-shaped structure of complex 1 and 2 suggest that Co(II) ions have two different coordinated modes, which are five coordination with O3NX environment and six coordination with O4N2environment. In addition, the electrospray ionization mass spectrometry (ESI-MS) analysis indicated that the ion molecular fragment of highest intensity was [Co4(L)6]2+, and there existed a high nuclear fragment peak of [Co7(L)12]2+. Interestingly, it was basically completely transformed into [Co7(L)12]2+two days later, so those two complexes were relatively stable in CH3OH. Magnetic characterization exhibited that complex 1 and 2 display field-induced single-molecule magnetic behavior, of which the energy hillsUeff/kBwere 28 and 20 K under direct-current field of 0.1 T, respectively.Keywords:tetranuclear;butterfly shaped;mass spectrometric;single-molecule magnet (SMM)

In recent years, multiple types of substrates have been applied for regulating cell orientation. Among them, surface topography patterns with grooves or ridges have been widely utilizing for cell culturing. However, this construction is still complicated, low cost-effective and exhibits some technological limitations with either “top-down” or “bottom-up” approaches. Here, a simple and green method was developed by utilizing butterfly wings (Morpho menelaus,Papilioulysses telegonusandOrnithoptera croesus lydius) with natural anisotropic nanostructures to generate cell alignment. A two-step chemical treatment was proposed to achieve more hydrophilic butterfly wings preceding cell culturing. Furthermore, calcein acetoxymethyl ester (Calcein-AM) staining and Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay results demonstrated the appropriate viability of NIH-3T3 fibroblast cells on those butterfly wings. Moreover, the cells displayed a high degree of alignment in each specimen of these wings. We anticipate that those originating from natural butterfly wings will pose important applications for tissue engineering.Keywords:butterfly wings;anisotropic nanostructure;chemical treatment;cell alignment

We report an effective process to transfer the scales of Morpho butterflies onto various substrates. Based on the difference in binding strength between molecular interactions and chemical bonds, this method provides photonic structure arrays with biological units, which are difficult to obtain otherwise.

This article reveals the source for two major themes in Madama Butterfly – one associated with Butterfly herself, the other with her patrimony. The assumption has been that Puccini based these themes on Japanese melodies, but his source was actually a Swiss music box playing Chinese tunes. Specific moments in the opera indicate that Puccini was aware of the titles of these tunes. The sound of music boxes in Butterfly and Turandot suggests previously unnoticed connections between these operas. The music-box melodies may be traced to Fritz Bovet's transcriptions. Puccini encountered ‘Jasmine Flower’ on these boxes, and in Turandot reaffirmed its status as the token of Chinese music.

A series of RbEu bimetallic ammonium metal nitrate hybrid analogues, [(CH3)3NCH2X]2[RbEu(NO3)6] (X = Cl, 1; Br, 2; I, 3), have been synthesized via solvent evaporation. This series shows similar cage-like perovskite frameworks, in which the cations are confined in the spaces enclosed by the hydrogen-bonding interactions. They display structural phase transitions and dielectric switchings between 243−303 K. Detailed single-crystal structural analysis of 1−3 reveals the change of the dynamics of the cation and the distortion of the [Rb4Eu4(NO3)12] anionic framework is the driving force for the structural phase transition. Meanwhile, the thermal and dielectric anomalies is verified by differential scanning calorimetry and dielectric measurements, respectively. Interestingly, the subtle change of cation significantly affects the switching temperature and dielectric behaviors, showing the typical ‘butterfly effect’ in these RbEu bimetallic hybrids. Notably, they also display excellent optical properties, that is, the Eu3+ ion plays as the activator of the photoluminescence property. Meanwhile, compounds 1−3 have phosphorescent characteristics and 1 has the highest fluorescence quantum yield (FQY) of 57.82 %. This finding will be evidently meaningful for exploring high-performance multifunctional switching materials for novel applications.

A simple method to create guided cellular orientation is illustrated by assembling fibroblasts on the dorsal side of M. menelaus wings. Moreover, by inserting the wing into tendon fibroblasts suspension at a tilt angle, guided cellular orientation concurrently with the cell density gradient is formed on the butterfly wings.

Fenton/Fenton-like reaction induced chemical dynamic therapy (CDT) has been widely recognized in tumor therapy. Due to the low efficiency of conversion from high-valent metal ions (M ( n +1)+ ) to low-valent ions (M n + ) in the Fenton/Fenton-like catalytic process, enhancing the conversion efficiency safely and effectively would create a great opportunity for the clinical application of CDT. In the study, a universal nanoreactor (NR) consisting of liposome (Lip), tumor cell membrane (CM), and bis(2,4,5-trichloro-6-carboxyphenyl) oxalate (CPPO) is developed to tackle this challenge. The CPPO was first discovered to decompose under weak acidity and H 2 O 2 conditions to generate carboxylic acids (R′COOH) and alcohols (R′OH) with reducibility, which will reduce M ( n +1)+ to M n + and magnify the effect of CDT. Furthermore, glucose oxidase (GOx) was introduced to decompose glucose in tumor and generate H 2 O 2 and glucose acid, which promote the degradation of CPPO, further strengthening the efficiency of CDT, leading to a butterfly effect. This demonstrated that the butterfly effect triggered by NR and GOx encourages Fenton/Fenton-like reactions of Fe 3 O 4 and MoS 2 , thereby enhancing the tumor inhibition effect. The strategy of combining GOx and CPPO to strengthen the Fenton/Fenton-like reaction is a universal strategy, which provides a new and interesting perspective for CPPO in the application of CDT, reflecting the exquisite integration of Fenton chemistry and catalytic medicine.

Scaffold nanotopography plays the most significant role in the mimicry of the in vivo microenvironment of the hepatocytes. Several attempts have been made to develop methods and substrates suited to growing hepatocytes into aggregates. Functional biomaterials, particularly biodegradable polymers, have been used in several studies aimed to develop improved scaffolds with ordered geometry and nanofibrous architecture for tissue engineering. However, there are still some limitation in their fabrication: it is not cost-efficient, is time-consuming, and exhibits some technological complications. The synthetic scaffolds are usually non-biodegradable and can be non-biocompatible compared to the naturally derived biomaterials. Here, we utilized a simple, cost-effective, and green method with two-step chemical treatment to get more selected hydrophilic butterfly wings fromMorpho menelaus,Papilio ulysses telegonus, andOrnithoptera croesus lydiusas a chitin-based natural scaffolds to growing hepatocyte aggregates. We established a three-dimensional (3D) in vitro model for culture of HepG2 cells and aggregate formation that maintained the hepatocytes function on these natural anisotropic microstructures. Cells cultured on these substrates show higher viability than those cultured on a two-dimensional (2D) culture plate. Methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay results revealed excellent viability of HepG2 cells onP. u. telegonuswings (fibrous area). The results also demonstrated appropriate cell activity, cell retention, and stable and functional expression in terms of albumin secretion and urea synthesis activity compared to the 2D monolayer culture of hepatocytes on the culture dish surface. With a slightly different degree, the other substrates also shown similar results. We anticipate that these natural anisotropic, biodegradable, and biocompatible substrates can maintain long-term hepatic culture as an in vitro 3D model for potential therapeutic applications and regenerative tissue applications. The model presented here provides a feasible alternative to the synthetic scaffolds and is expected to be more reliable for 3D organotypic liver culture models based on such scaffolds.Keywords:organotypic culture models;cell aggregate;HepG2;3D scaffolds;anisotropic microstructure

Polyvinylidene fluoride (PVDF) porous membranes with superwetting amphophilic surfaces were prepared by in situ cross-linking polymerization of varied triethoxyvinylsilane (VTES) and N-vinyl-2-pyrrolidone (VP) composition ratios during none-solvent induced phase separation (NIPS) processes, utilizing template stripping method. The extreme powers of surface roughness , in amplifying the finite differences in chemical composition of initial dope solution to the properties of the resulted membranes, were revealed by comparing the structures and surface properties of these membranes with super rough surfaces, to their analogues with medium-rough surfaces and films with smooth surfaces. “Butterfly Effect” was observed on the water/oil separation capability of the formed PVDF membranes from the finite variation on the initial chemical composition caused by the change of VTES/VP molar ratio in the dope solution from 0 to 0.33, 0.38, 0.43, 0.48 and 0.53. Huge variations in the oil and water fluxes and removal efficiencies in separating water-in-oil and oil-in-water emulsions of the formed membranes from the “Butterfly Effect” were studied relating to their differences in water-in-air contact angles, oil-in-air contact angles, oil-in-water contact angles and water-in-oil contact angles as well as pore sizes and surface roughness.

Recently, surface enhanced Raman spectroscopy (SERS) has been widely studied for chemical and biological sensing. SERS substrates combined with photonic architectures have attracted more and more attention. Photonic architectures in butterfly wings are too complicated to fabricate with either “top-down” or “bottom-up” approaches. Herein, we developed a simple, reproducible, inexpensive and green method to fabricate SERS substrates from different butterfly wings where the component chitosan/chitin was utilized as in situ reducer to synthesize gold nanoparticles in natural 3D photonic architectures. The SERS performances of three butterfly wings are compared. And the results show that a SERS substrate based on M. menelaus is better than the other three substrates, which could detect 10−9 M 4-ATP and has the lowest RSD and moderate SNR. In situ synthesis of AuNPs in butterfly wings with photonic architectures paves the way for fabricating multiple SERS substrates based on natural materials.
