Fruit use and fruit processing by euphonias, specialized avian frugivores

Oikos, EarlyView.
Euphonias (Neotropical passerines in the genera Euphonia and Chlorophonia) form the quintessential example of a specialized avian frugivore, combining a high reliance on fruit as food and the restriction of fruit taxa exploited. To understand their specialization, we explored the integration of fruit morphological and nutritional traits with their ...

The predatory behavior of ants: an impressive panoply of morphological adaptations

Insect Science, EarlyView.
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

Dimorphic cocoons of the cecropia moth (Hyalophora cecropia): Morphological, behavioral, and biophysical differences

PLOS ONE, 2017
The larvae of the giant silk moth (Hyalophora cecropia) spin strikingly dimorphic, multilayered cocoons that are either large and fluffy (baggy) or significantly smaller and tightly woven (compact). Although these cocoon-morphs share the same function (i.e., housing for pupal to adult development during overwintering), previous work has been unable to ...

Host preferences of non‐native Acalolepta aesthetica (Coleoptera: Cerambycidae) on the Island of Hawaiʻi

Agricultural and Forest Entomology, EarlyView.
Acalolepta aesthetica is a non‐native cerambycid established on the Island of Hawaiʻi. We show its preferred hosts are woody species that are highly valued for agricultural, horticultural and cultural uses. We used a resource selection function to estimate host preferences and found that kukui (Aleurites moluccanus), the state tree, was preferred ...
