Congratulations Brian, your beautiful Cinnabar Moth has been chosen to illustrate today's fact for National Moth Week 2017:

"National Moth Week 2017 continues! Thanks to all of you who have submitted moths spottings so far. In honor of this year’s focus on tiger moths, Project Noah ranger, National Moth Week organizer and Cornell University entomology student Jacob Gorneau is bringing us daily interesting facts about tiger moths (Erebidae: Arctiinae):
"Yesterday we discussed the ability of some tiger moth species to jam bat sonar. Some tiger moths are also very chemically defended. Some moths may sequester toxic plant chemicals, while others break down toxic chemicals found in their host plants and create new toxins for defense. Many organisms that are chemically defended also have aposematic, or warning coloration to indicate to predators that they are chemically defended.
The Cinnabar moth (Tyria jacobeae) is a moth which is chemically defended and aposematically colored, meaning it has warning coloration. It is native to Europe but was introduced in Oregon where is has been a successful biocontrol agent in the management of the invasive tansy ragwort".
Tyria jacobaeae spotted in Washington, USA, by Brian38
