Prey Interception: Predictive and Nonpredictive Strategies

January 1988

W. Mitchell Masters

Insectivorous bats use echolocation as their sole source of information to detect, locate, approach and capture flying insects. Although the sequence of behaviors they go through is relatively sterotyped (Webster, 1967b; Kick and Simmons, 1984), much remains unknown about how bats accomplish this incredible feat. I am particularly concerned here with what bats do with the positional information ... [Show full abstract] they obtain about a target by echolocation: how does a bat choose its flight path so as eventually to intercept the target?

Adaptation de la fleur entomophile de l'Anthyllis vulneraria L. à l'autogamie

July 2014 · Bulletin de la Société Botanique de France

La fleur de l'Anthyllis vulneraria L. était considérée comme adaptée à la fécondation croisée par les insectes. Une étude détaillée de l'organisation florale, des mécanismes de pollinisation et du mode d'intervention des insectes butineurs, met au contraire en évidence une remarquable adaptation à l'autogamie.SummaryThe flowers of Anthyllis vulneraria L. were considered as adapted for cross ...

A detail study of floral organization; the mecanism of pollination and the ways of insect participation, has shown, in contrary, an evidence of efficent adaptation of autogamy.

Self-selection of optimal diets by insects

January 1991

Self-selection of diet implies a continuous regulation of food intake that involves frequent shifts between food, shifts which are assumed to be nonrandom and beneficial. A distinction is drawn with insects between diet switching between instars and self-selection within instars. The author reviews criteria for self-selection; indicates the potential for the phenomenon (insect dietary ... [Show full abstract] requirements, variable nutritive value of food); then expands how dietary self-selection may be achieved by insects and other arthropods. Behavioural and physiological control of self-selection are explicitly examined. -P.J.Jarvis

Dohrniphora (Diptera: Phoridae) from the Miocene Mexican and Dominican ambers with a paleobiological...

October 2017 · Insect Systematics & Evolution

Male specimens of the phorid fly genus Dohrniphora Dahl from Miocene Mexican and Dominican amber are revised and described. This is the first systematic revision of the fossil species, and 11 new species are recognized from two Dohrniphora groups: those with and without large hind tibial setae. The group lacking hind tibial setae is notably more diverse and frequent in amber than those with such ... [Show full abstract] setae. Swarming behavior in Dohrniphora females is noted for the first time. Probably, these females were frequently attracted in large numbers to dead and decaying insects and other animals trapped in resin. Another phorid genus with similar habits, Puliciphora , frequently co-occurs in amber pieces containing Dohrniphora specimens.
