Once this has been installed, you will have a black screen with a call button. You will just need to click call and it should connect into the VMP.
- For Deakin staff and students, please join via Skype for Business (Lync) – if you have office installed you may already have Skype for business or Lync installed. You just need to look for it on the start menu. If you find it, you can log into skype using your Deakin email and password and then dial 36958.
- Could not log in? More info on how to connect is available HERE or HERE.

As a courtesy, we request that when connecting to the seminar that you mute your microphone unless you are required to speak, this would ensure that the sound from the speaker to the audience is not disrupted by feedback from your microphone – thank you!
Many insects change colour during ontogeny and, in some, this can be explained by different selective pressures acting on highly dissimilar adult and larval forms. However, some insects, such as many true bugs (Heteroptera), retain similar body shape and share similar predators and habitats through ontogeny. Many of these species also release defensive secretions which are advertised with bright colours, and are thus considered aposematic.
In this talk I will present the most recent results on two projects related to this question. We use a comparative approach and predation experiments to understand what drives the evolution of colour changes in butterflies and in bugs.
Iliana completed her Undergrad and Masters at the Universidad de los Andes in Colombia, where she studied evolution of colour in poison frogs. In 2012 she moved to Australia to complete her PhD at the Australian National University. She then moved to Melbourne as a McKenzie Fellow.
Iliana’s main interest is the macroevolution of animal behaviour and coloration, and she uses phylogenetic comparative methods in combination with field and lab experiments to answer broad questions in ecology.
