Construction of the previously mentioned butterfly Y-Tube Olfactometer is thankfully now complete.
As you will see, I've even got the pastes ready in preparation for positive control testing. All we now need are the specimens. I will be digging out some Aglais urticae from local sheds and garages for testing of the equipment over the winter months, but apart from this, roll on the 2015 A.iris/A.ilia flight season. Where are all the male images just when you need them? I really can't wait to start playing around with this, hopefully we'll get some excellent data. More on this as the results unfold.
