Entomology (Study of Bugs)/Wondering if it is a spider


Hello Ed,

Recently I have been getting bites at night, but I've never found any bugs in my bedroom.
Today I was in the guest room and I found this bug next to the window, around 7:30 pm. I think it is a spider, but I couldn't identify just looking up on the internet. It has been really stressful getting all these bites and not sure what is biting me... By the way, my boyfriend shares the bed with me almost every night and he hasn't gotten a single bite. I am really afraid this could be a bed bug or a mite.

Thank you very much for your help, I appreciate it.



Dear Rose - It is nearly impossible to determine the cause of 'mystery bites' without actually seeing/catching the culprit(s) in the act of biting. Given your location, I would not be surprised if it turned out to be a mosquito or other biting fly that gained entry during the night. If you fins anything else that you suspect, please try to obtain a close-up photo that you could attach to another question.

Hope this helps,

Will accept most questions in general entomology, including those related to medical entomology, taxonomy, ecology, arthropod surveillance, and pest management. If you are requesting a 'mystery bug' identification, PLEASE either attach an image to your question, or post an image on a web page (such as Flickr) so that I can look at it, as verbal descriptions frequently are insufficient for a definitive identification.
