Unknown - Smear Only

N/A

Likely hematophagous (blood-feeding) based on the red smear.

N/A

There is no insect visible in this photo, only a reddish stain on a paper towel or tissue. While red smears like this are often associated with squishing blood-feeding pests like bed bugs or mosquitoes, it is impossible to identify a specific insect without seeing the bug itself. It could also just be a stain from something else entirely.
