San Francisco Apartment Dweller - Trogium pulsatorium

San Francisco Apartment Dweller - Trogium pulsatorium
San Francisco, San Francisco County, California, USA
July 5, 2014
Size: 2-3 mm
Found it crawling around the baseboard in a third-floor apartment. Originally thought it was a bedbug nymph, but inspector found no other evidence of bedbugs and stated that the head looked wrong. Inspector couldn't tell us what it might be. Can any of you?


- Color is actually a very light brown.
- Abdomen has light horizontal stripes (or is maybe just segmented).
- Antennae appear to be slightly shorter than the body.
- Appears to have six legs (front of abdomen, mid-thorax, front of thorax?)
- Background is cardboard from a tissue box.
- We think we found one other similar bug, but can't find it now.
- We've been getting small bedbug-like bites for months but also sometimes have mosquitos and haven't seen this bug before today.

i wish the pic were sharper but keeping it in the guide anyway
Moved from ID Request.

Y'all are amazing.

Out of curiosity, I looked up Trogium pulsatorium online and found it on Wikipedia listed under the superorder Psocoptera. Is there a particular reason this isn't listed here under its superorder, or are superorders just generally not worth listing?

any number of classifications exist in various sources
on this site we follow(1) as the most authoritative; in general, Wikipedia is not a reliable source of taxonomic information... or historical, for that matter

more likely the cosmopolitan Trogium pulsatorium

totally incapable of biting

ID confirmed by E.L. Mockford

Well... At least I got the Suborder right
EDIT: A second look reveals that I wasn't even that close. Sheesh!

Booklouse, I reckon
