Background. The ‘whirling’ defensive behavior of Pholcus ancoralis (L. Koch, 1865) was studied in a forest and laboratory in Mo’orea, French Polynesia. This behavior involves fast web-borne gyration to dissuade predators and is widespread in the Pholcidae family....

In some insects, males produce costly ejaculates that reduce the typical sexual imbalance in potential reproductive rates thus influencing the mode and intensity of sexual selection. In Lepidoptera, in particular, males tend to invest heavily in mate searching,...

Historically, handling insects usually involved their being killed as early studies used these organisms for work on genetics, physiology and/or pesticide bioassays. With the advancement of these research topics, the development of behavioral studies and the sensitivity...

Habituation, a form of non-associative learning, has several well-defined characteristics that apply to a wide range of physiological and behavioral responses in many organisms. In classic patch time allocation models, habituation is considered to be a major mechanistic...

Urbanization is an increasingly pervasive form of land transformation that reduces biodiversity of many taxonomic groups. Beetles (Order: Coleoptera) exhibit a broad range of responses to urbanization, likely due to the high functional diversity in this order....
