Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations
Biotropica, Volume 57, Issue 6, November 2025.In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

The magnitude of cryptic insect diversity in one tropical rainforest
Insect Conservation and Diversity, Volume 18, Issue 6, Page 1163-1174, November 2025.We detected 214 cryptic species out of a total of 2006 species (10.6%) examined from 22 focal insect taxa in 1500 ha tropical rainforest in Panama. The percentage of cryptic species varied greatly among assemblages (0%–19%), with half of the assemblages devoid of cryptic species and the highest proportions of cryptics in Pieridae and Formicidae ...
