Hello and greetings. I am enclosing the photo if a bug I discovered  biting my inner leg. It its small so please pardon the image if it is not extremely high quality. The colors are what appears dark brown and stand and clear perhaps some yellow tint. The bug left a small puncture wound. I just want to ensure I don't need to be concerned about the bite. Thank you for your time.

Dear Ashley - First off, please let me apologize for the delay in responding to your question; I was away from home from Thursday through yesterday evening, and forgot to put myself on 'Vacation' status. That aside, what you have here is completely harmless - it is a leaf beetle (Coleoptera: Chrysomelidae) in the subfamily Cassidinae (tortoise beetles); it appears to be a clavate tortoise beetle (Plagiometriona clavata) - see http://tinyurl.com/2emdkpo for an image. They feed primarily on plants in the family Solanaceae (potatoes, peppers, eggplant, etc.) - see http://tinyurl.com/lazcqk7 for morre detailed information.

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.
