The past two mornings I've had the privilege to assist famous birder and author, Jon Dunn, with his warbler workshop presented as part of the Rio Grande Valley Bird Festival. The warblers have been a bit thin these two days but we did find some cool butterfles. This Great Purple Hairstreak at Anzalduas was new one for me.
Another new one for me, north of Mexico, was this beat up Many-banded Daggerwing I found at Frontera. What's really cool is that is was a life butterfly for Jon. This is a real honor for me considering that Jon Dunn has found literally thousands of life birds for people throughout the years.
