Hello and thanks for wonderful website. Can you help me identify this, slightly bigger than an inch long, insect which I have never ever seen in Laguna, been here 50 years, and seeing many of these this week. Very fast moving, daytime flier. Best regards!

Ctenucha multifaria

Dear Tanya,
Thanks for your kind words.  This is a diurnal Tiger Moth,
Ctenucha multifaria, and we identified it thanks to this BugGuide descriptions:  “Distal tip and entire costal edge of forewing narrowly white-marginned. Patagia** entirely black.”  Diurnal Tiger Moths in the genus Ctenucha are very effective wasp mimics.
