Lesvos is also well-known for its orchids. Below is a complete list of orchids found on the island. In my book, A Birdwatching Guide to Lesvos, there is also a checklist which includes local flowering periods for many of commoner species.

Paul Manning (Wildlife of Lesvos) has built an orchid site guide. He has annotated a map of the island to show key sites. This includes lists of species found at each site with some notes on flowering periods for rarer or sought-after species, and species' names within the site lists linked to his own photos on his online flickr album. Its a great resource and one I'm sure that anyone interested in orchids will want to use when on the island. The online Google Map is best viewed in map mode.
Highlighted names will link to individual species images on Paul Manning's Lesvos orchid flickr gallery. Note, some species have more than one photo so its worth looking at Paul's site in more detail.
