| Scorpions rely predominantly on mechanosensory and chemosensory organs to guide their orientation behaviors. Once sensory organs are affected by the presence of dirt such as clay or prey bodily fluid, scorpions may display a cleaning behavior to reduce or eliminate its influence on their sensory capabilities. In the laboratory, cleaning behaviors of two buthid species, Mesobuthus eupeus (Koch, 1839) and Mesobuthus caucasicus (Nordmann, 1840), and one euscorpiid species, Scorpiops luridus Zhu Lourenço & Qi, 2005 from China, were observed before and after feeding. Moreover, two distinct cleaning behaviors in Scorpiops luridus and three in Heterometrus petersii (Thorell, 1876) (Scorpionidae) were noted for several times during daily activities. Based... |

| In the present study 387 dung beetles (Coleoptera: Scarabaeidae) were surveyed at the Serra do Japi, in the Atlantic Forest in São Paulo State, with four baited pitfall traps during the months of December, 1998, and January, 1999 during eight 24 hour cycles. A total of 30 species were identified and temporal variation in activity patterns among the species shows a specialization in the use of food resources: 9 species were classified as nocturnal and 13 as diurnal. The daily activity pattern of dung beetles does not necessarily correspond to the taxonomic classification, but is strongly related to the colouring of species, determined by predominant elytra colour: nocturnal species have 89 % more chances of being black as opposed to colourful. Black... |

| Behavioral and physiological mechanisms of thermoregulation in ectotherms are conditioned by thermal constraints. These mechanisms may be even more restrictive when environmental conditions are unfavorable for individuals, especially when sexual dimorphism segregates the sexes spatially. In order to understand behavioral and physiological regulation mechanisms, we investigated the thermal biology of Phymaturus palluma (Molina, 1782), a sexually size dimorphic, high-mountain lizard that inhabits extreme climatic conditions. P. palluma showed a bimodal activity pattern, a major peak in the morning (11:00-13:30h) and in the afternoon (15:30-18:00 h). The lizards were more active when substrate temperatures were between 25 and 28º C. The highest abundance was... |

| Euglossinae bee fauna of two areas of terra firme forest near Manaus, Amazonas, Brazil was compared. Over a twelve-month period collections were done fortnightly, between 7:00 a.m and 5:00 p.m, using traps with eight kinds of scent baits. The traps were placed in the understory and in tree crowns. The majority of species and specimens was most active between August-December, near the beginning of the rainy season in this region. The bees were most active from 9:00 a.m. until 4:00 p.m., while air temperatures were between 24.5-27ºC, but there was a decline in this activity when air temperature varied above or below of this range. There were differences in the seasonality and in the daily activity patterns for the two areas studied but these differences were... |
