What do you think this is? Found on bedroom curtain. Spouse did return from trip but also has 2 welts that look like tiny dots inside a big welt on torso & back that itch some. We live in Colorado, it’s been warm here almost 70. We have pets & doors open often.

Dear Bugged Out,
This is a Multicolored Asian Lady Beetle,
Harmonia axyridis, a highly variable species that was introduced from Asia many years ago.  It is a species prone to forming large aggregations and also known for moving indoors as the weather cools to hibernate.  Its proliferation is believed to be a contributing factor to lower populations of native Lady Beetles.  It is possible to be bitten by predatory Lady Beetles, but we suspect the welts on your spouse are from another creature.  See BugGuide for more information on the Multicolored Asian Lady Beetle.
