Ctenus medius Keyserling, 1891 is a common species in several spots of Mata Atlântica, however there is a great lack of studies in all aspects of its natural history. This work aims to elucidate aspects of ecotope preference compared to large spiders, and to provide data on the development of chromatic patterns during its life cycle. The observations on the behavior of C. medius were done in the campus of Centro Universitário de Barra Mansa (UBM) by means of observations and nocturnal collections using cap lamps. For observations on the development of chromatic patterns, spiderlings raised in laboratory, hatched from an oviposition of a female from campus of UBM, and others spiderlings collected in field were used. The field observations indicate that: C. medius seems to prefer ecotopes characterized by dense shrub vegetation or herbal undergrowth; Lycosa erythrognatha and L. nordeskioldii seems to prefer open sites; Phoneutria nigriventer seems to prefer shrub vegetation and anthropogenic ecotopes as rubbish hills; Ancylometes sp. seems to prefer ecotopes near streams. Concerning chromatic patterns, it was observed that males and females show well distinct patterns during the last two instars, allowing distinction by sex without the use of a microscope. Through chromatic patterns it was also possible to draw a distinction between C. medius and C. ornatus longer that 3 mm cephalothorax width. 69 specimens of C. medius (males and females) collected in the campus of UBM did not show a striking polymorphism in chromatic pattern, but one among 7 adult females collected in National Park of Itatiaia, showed a distinct chromatic pattern.

A knowledge of life cycle and natural history are often important prerequisites to studies of population biology in butterflies. Although studies on the systematics and broad distribution patterns of that familiar New World Tropical group, the Ithomiinae, have been conducted (Seitz, 194; Fox, 1956; Fox, 1968), a lot remains to be known about the biology of many species in Central America. This is surprising in light of the considerable interest in these butterflies as members of mimicry complexes. In this spirit, this paper summarizes life cycle and natural history data on a clear wing ithoreiine Hymenitis nero (Hewitson) (Nymphalidae: Ithomiinae) in Costa Rica. Similar studies of several other sympatric ithomiines have either been completed (Young, in prep.) or begun, as a preliminary step towards understanding the local patterns of diversity of this family in selected tropical plant communities.

This paper summarizes the life cycle and some aspects of natural history of the tropical pierid, Dismorphia virgo (Dismorphiinae) in Costa Rica. The precise taxonomic status of the butterfly in Central America has not been established, and it may represent a variable northern isolate of the common South American D. critomedia. Therefore, independent of whether the Central American form discussed in this paper has achieved full species status as the more northern virgo or is a subspecies or variety of critomedia evolving towards species status, this paper provides new information on the biology of the butterfly in Costa Rica. The establishment of precise taxonomic position awaits further study, and for the present purpose, I refer to the butterfly as D. virgo.

Parasites are more numerous than non-parasitic species and have evolved in virtually all groups of organisms, such as viruses, prokaryotes (bacteria), protozoa, fungi, nematodes, flatworms, acantocephalans, annelids, crustaceans, and arthropods (crustacea, mites, ticks, insects). These groups have adapted to the parasitic lifestyle in very many ways. Evolution towards parasitism has also followed different routes. Initial steps such as phoresy, followed by later consumption of the transport host, are plausible evolutionary routes. Alternatively, formerly free-living forms have become commensals before evolving parasitism. Complex life cycles with several hosts evolved by scenarios such as upward (adding a new host upwards in the food chain), downward, or lateral incorporation, driven by the advantage of extending growth phases within hosts and increasing fecundity. Examples are digenea; other parasites have added vectors to their life cycle.

The butterfly Actinote brylla was described by Oberthür in 1917; since then, no work describing the life cycle of the species has been officially published. This paper aimed to describe the life cycle of A. brylla. The early stages, larval host plant and oviposition behavior were described after the creation of individuals collected in the region of “Baixada Santista”, the coast of the State of São Paulo, Brazil. Actinote brylla uses Mikania lundiana as a host plant, with eggs being placed on the abaxial face of the leaf and ranging from 12 to 836 eggs in a cluster. Egg is barrel shaped with 18 to 22 longitudinal grooves and weakly marked horizontal ridges. Soon after laying, eggs are light white-yellowish gradually changing to red during the first 72 hours, ovules non-fecundated remains yellow. The caterpillars go through seven instars until pupation, the larvae are gregarious until the penultimate instar. The pupa is yellowish green in the early hours, after hardening, the coloring is cream with dark brown markings on wing cases and abdomen. The duration of all life cycle (egg to adult) ranged from 93 to 123 days. Key words: Mikania lundiana, superoviposition, egg cluster, Chaetotaxy

Improve Attitude

Public opinion is important in obtaining support for the conservation of biodiversity, and invertebrates have a "public relations problem" because -for reasons that are both cultural and biological- they are poorly known and often unpopular. In this article I present the results of an experiment on the power of a short lecture to improve attitude towards invertebrates, using the case of velvet worms. Velvet worms are "living fossils" that have inspired a wide range of cultural expressions, probably because of the adhesive net they use to capture prey. For the experiment, a group of 141 Costa Ricans, aged 10 to 58 years old, rated their reaction to a color photograph of Epiperipatus biolleyi, a Costa Rican species of velvet worm, before and after a five-minute lecture about the natural history of the worm. Even before the treatment, most of the respondents had a correct idea of the animal's anatomy (84%); supported the use of public funds to conserve it (71%); and more than half perceived the worm in a positive way (58%). They stated that they were willing to donate a mean of US$7,00 from their own pocket for the worm's protection (six times more if they had university education); and were less likely to reject the worm if they kept pets at home. Gender, age and education did not have any effect on most variables of attitude and knowledge. Compared with the control group, the group that received the lecture had a 17% improvement in attitude. The Costa Rican educational system, focused on nature and its conservation, can explain the generally good attitude and knowledge of invertebrates found in this study; and a five-minute natural history lecture can produce a significant improvement in perception of an animal that is generally unattractive: a worm.

A description is given of the waxworks made by the Italian physician Angelo Maestri (1806–1889), preparator, taxidermist and model-maker at the Museum of Natural History of Pavia University where the majority of his wax models are held today. Maestri's main works deal with the anatomy, physiology and pathology of the silkworm, the morphology of mushrooms and the poison fangs of snakes. He also made models of the life cycle of the nematode Trichinella spiralis and of the blood circulation in some vertebrates. Several preparations in wax by Maestri are held in other scientific institutions in Italy.
