Three tour members met with Paul at Heathrow’s Terminal 5 for the 8.25am British Airways flight BA0602, to Pisa, Galileo Galilei Airport. Upon arrival, we quickly completed immigration formalities, collected our luggage and made our way out to the Arrivals hall, where we met with Gil, who had made his own way to Pisa. We now took the shuttle bus to the car rental area, where we collected our minibus. Joining the main Pisa to Florence motorway east towards Empoli, we then turned south, heading for San Gimignano. As we went, we saw Black Kite, Barn Swallow and Grey Heron, and many of the verges were red with patches of Hedysarum coronarium (Italian Sainfoin). We also spotted a small group of four Fallow Deer. A light lunch was taken at a service area. We spent an hour and a half exploring the medieval walled town of San Gimignano, before continuing past Siena and joining the E80 south towards Grosseto. Jackdaws and Starlings were noted as we went. Passing Grosseto, we left the road at Alberese and soon arrived at the lovely comfortable La Fattoria Il Duchesco, our base for the next five nights, where we were met by our host, Fabio.

  • Colourful Butterfly Wings: Scale Stacks, Iridescence and Sexual Dichromatism of Pieridae Doekele G
    158 entomologische berichten 67(5) 2007 Colourful butterfly wings: scale stacks, iridescence and sexual dichromatism of Pieridae Doekele G. Stavenga Hein L. Leertouwer KEY WORDS Coliadinae, Pierinae, scattering, pterins Entomologische Berichten 67 (5): 158-164 The colour of butterflies is determined by the optical properties of their wing scales. The main scale structures, ridges and crossribs, scatter incident light. The scales of pierid butterflies have usually numerous pigmented beads, which absorb light at short wavelengths and enhance light scattering at long wavelengths. Males of many species of the pierid subfamily Coliadinae have ultraviolet-iridescent wings, because the scale ridges are structured into a multilayer reflector. The iridescence is combined with a yellow or orange-brown colouration, causing the common name of the subfamily, the yellows or sulfurs. In the subfamily Pierinae, iridescent wing tips are encountered in the males of most species of the Colotis-group and some species of the tribe Anthocharidini. The wing tips contain pigments absorbing short-wavelength light, resulting in yellow, orange or red colours. Iridescent wings are not found among the Pierini. The different wing colours can be understood from combinations of wavelength-dependent scattering, absorption and iridescence, which are characteristic for the species and sex. Introduction often complex and as yet poorly understood optical phenomena The colour of a butterfly wing depends on the interaction of encountered in lycaenids and papilionids. The Pieridae have light with the material of the wing and its spatial structure. But- two main subfamilies: Coliadinae and Pierinae. Within Pierinae, terfly wings consist of a wing substrate, upon which stacks of the tribes Pierini and Anthocharidini are distinguished, together light-scattering scales are arranged.

  • Flexural Stiffness Patterns of Butterfly Wings (Papilionoidea)
    35:61–77,Journal of Research1996 (2000) on the Lepidoptera 35:61–77, 1996 (2000) 61 Flexural stiffness patterns of butterfly wings (Papilionoidea) Scott J. Steppan Committee on Evolutionary Biology, University of Chicago, Chicago, IL 60637, USA., E-mail: [email protected] Abstract. A flying insect generates aerodynamic forces through the ac- tive manipulation of the wing and the “passive” properties of deformability and wing shape. To investigate these “passive” properties, the flexural stiffness of dried forewings belonging to 10 butterfly species was compared to the butterflies’ gross morphological parameters to determine allom- etric relationships. The results show that flexural stiffness scales with wing 3.9 loading to nearly the fourth power (pw ) and is highly correlated with wing area cubed (S3.1). The generalized map of flexural stiffness along the wing span for Vanessa cardui has a reduction in stiffness near the distal tip and a large reduction near the base. The distal regions of the wings are stiffer against forces applied to the ventral side, while the basal region is much stiffer against forces applied dorsally. The null hypothesis of structural isom- etry as the explanation for flexural stiffness scaling is rejected. Instead, selection for a consistent dynamic wing geometry (angular deflection) in flight may be a major factor controlling general wing stiffness and deformability. Possible relationships to aerodynamic and flight habit fac- tors are discussed. This study proposes a new approach to addressing the mechanics of insect flight and these preliminary results need to be tested using fresh wings and more thorough sampling. KEY WORDS: biomechanics, butterfly wings, flight, allometry, flexural stiff- ness, aerodynamics INTRODUCTION A flying insect generates aerodynamic forces primarily through the ac- tive manipulation of wing movements and the “passive” morphological prop- erties of deformability and wing shape.

  • Interesting Early Stages of Some Sri Lankan Moths Typical Moth Life Cycle
    Interesting early stages of some Sri Lankan Moths Typical Moth Life Cycle A Cocoon is a casing of spun silk produced by many insects to form a protective covering for the Pupa. Many Moth Caterpillars for example produce silk cocoons. Cocoons can be of various types, from hard to soft, with various colours dependent on the species involved. Wingless Females Some female moths of the Subfamily Lymantriinae are flightless. Male Female Orgyia sp. Lymantria sp. Life Cycle of Lymantria ampla Life cycle of Fir tussock moth (Orgyia detrita) Ant-mimic Moth caterpillars • Caterpillars in the moth genus, Homodes Guenée have been documented to be closely associated with weaver ants, as well as resembling them in terms of morphology and behaviour (Shelford, 1902, 1916; Kalshoven, 1961; Common, 1990; Holloway, 2005). In Sri Lanka, at least three species have been previously recorded • Homodes fulva • Homodes crocea Homodes crocea • Homodes vivida Dorsal (a) and posterior (b) views of the raised rear end of the caterpillar, Lobster Moth (Stauropus alternus) • First instar larva is a very good ant mimic both in appearance and behaviour • Resting posture of its mid instar look like an irregularly curved, dead leaf. • This resemblance to dried or dead leaf debris is certainly applicable to the later instars as well. Bagworms (Psychidae) • The bagworm family (Lepidoptera: Psychidae) includes approximately 1000 species, all of which complete larval development within a self enclosing bag. • In Sri Lanka 23 species have been recorded in this family • Some bagworms are specialized in their host plants (monophagous) , while others can feed on a variety of plant species (polyphagous) Eumeta variegata • A bagworm begins to build its case as soon as it hatches.
