Lophocampa roseata (Rosy aemilia)

I spent a good part of the day combing through my insect photos from the past 9 years. There are thousands. Finally, I found the ones I was searching for. I credit Victoria Compton on San Juan Island, WA  for helping me out on this one. She sent a photo the other day to my email with a caterpillar and had suggested an ID. Not only was she correct, but in ID’ing the caterpillar, it enabled me to match up one of my adult moth photos that had been sitting around nameless since 2016. The photos I found today were of the same caterpillar that had been a mystery to me since 2013. It’s a nice “aha” moment when you connect the dots! Below are the pics for you to see.

This is a Tiger moth in the family Erebidae, subfamily Arctiinae. The scientific name is Lophocampa roseata (also known as the Rosy aemilia). It was first described by Francis Walker in 1868.  They are found in Western Oregon and Washington as well as in Southwestern B.C. and are associated with habitats of conifer forests and maple trees. The sources I checked list them as somewhat rare and Natureserve lists them as “critically imperiled.” So, I guess we have another beautiful Lepidoptera on San Juan Island to care for along with the Marble Butterfly!

***Critically imperiled Tiger Moth. Please post/email photos if you live in San Juan County, WA and come across one in the adult or larval stage.  Thanks!

    "BUGGING" YOU FROM FRIDAY HARBOR!

    I love beetles and keep bees! In my free time, I enjoy photography (mostly bugs) and documenting insect species found on San Juan Island. I have limited availability for local, onsite beekeeping consultation and hive inspection, honey bee removal/swarm collection as well as phone/skype consultation.
