Butterflies released in Finland contained parasitic wasps – with more wasps inside

When caterpillars of a beautiful butterfly were introduced on to the tiny island of Sottunga in the Åland archipelago, scientists hoped to study how the emerging butterflies would disperse across the landscape. But researchers did not realise that their introduction of the Glanville fritillary (Melitaea cinxia) led to the emergence of three other species on […]

Imagine a plant. Now remove the soil, for it’s not essential. In fact, an estimated one-tenth of all plant species have liberated themselves from soil and evolved into epiphytes—plants that grow on other plants. Although growing on others can seem parasitic, botanists have traditionally acquitted epiphytes of stealing from their hosts—except for the parasitic mistletoe—regarding […]

Neonicotinoid pesticides ‘damage brains of bees’

Neonicotinoid pesticides ‘damage brains of bees’

Commonly used pesticides are damaging honey bee brains, studies suggest. Scientists have found that two types of chemicals called neonicotinoids and coumaphos are interfering with the insect’s ability to learn and remember. Experiments revealed that exposure was also lowering brain activity, especially when the two pesticides were used in combination. The research is detailed in […]
