The findings help to fundamentally alter our understanding of insect migration and could also have an impact on how the spread of pests and disease-carrying insects is dealt with. Behind the study is an international group of researchers, including Dr Pettersson from Lund University.
The researchers have used various methods and results from both Britain and Sweden to see that almost six times as many Silver Y moths travel south after the summer as travel north in May to June.
“The spring generation migrates to Northern Europe and their offspring migrate south again”, says Lars Pettersson.
For the Silver Y and other migratory moth and butterfly species, this means that they, just like migratory birds, can make use of the long summer days and the abundant supplies of food in the north.
According to Lars Pettersson, it is important to be able to monitor migratory insects, not only to monitor pests, but also because they are an important source of food for many birds and small mammals. In addition, it has just been shown that moths in the Noctuidae family, such as the Silver Y, could play an important role as pollinators, observes Lars Pettersson.

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.
So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...
Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
