Found in my laundry room

What bug makes a bit that looks like this?

My mom was sitting outside (Vermont) and felt something bit her. Swiped it away and it looked like this. Any idea what type of bug could make this bite?

Who is this friend?

I’m in Rhode Island. He just kept running down my steps away from me throwing him off of each one. He flipped himself over and curled up like he was dead when I stopped to look at him and then he jumped up and started running again 😅 I have a lot of Orbweavers and jumpers of all types, but this guy is new to me. The flat head is throwing me off.

What kind of spider is this? (MA)

What is this guy?

What bug is this one?

Tried to reverse image it but no results whatsoever

Have these inside and outside Sheffield Lake Ohio

I have found these guys inside in one particular room only (a half bathroom linen closet). They also hang out on the front porch. Any idea what it is? Thanks in advance!

Didn’t see a bug near by. Is this a nest or egg of sorts?

I need to know what this bug is for a school ecology project

Found in my sisters house and possibly biting her all over

My sister thought she had bed bugs but a quick google search disproved that. I haven’t seen them in person but I’m told they are “smaller than a thistle seed”. Any idea what these are and if they could be the culprit for the bites all over her?
