Nectar plant preferences of Hemaris (Sphingidae) on co-occurring native Cirsium and non-native Centaurea (Asteraceae) inflorescences

open access: yesJournal of Pollination Ecology, 2014
Preferences for certain nectar plants by moth pollinators have not been extensively studied, particularly seasonal switches in nectar diet. The genus Hemaris, found throughout North America and parts of other continents, is a useful new system to address

Preference‐performance relationship in the thistle tortoise beetle: Implications for its realised host range

open access: yesEcological Entomology, EarlyView.
There was a positive relationship between adult preference and larval performance. However, the strength of the relationship ranged from weak to strong depending on the measure of adult preference. The adult beetle showed substantial flexibility in host plant selection and equal performance across most thistle hosts.

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...
