We are just back from another short sampling trip in Colombia. This time we were near the town of Bahía Solano, between our previously furthest north sampling location in Colombia and our furthest south location in Panama. Emma’s analysis of the butterflies we collected last time suggests that that is a sharp transition from blue to black wing colour around the border between Colombia and Panama, so getting samples from this region could be key to working out where this transition happens and how sharp it is, as well as finding genes that are associated with the colour.
There are no roads in this area so we did a lot of travelling up and down the coast in a small motor boat. All the logistics were again organised by Carolina and Camilo from the Universidad del Rosario, along with local guides, so we are hugely grateful to them!
