Can an insect kill skin pigment on contact?

Has anyone ever heard of something like that. I vaguely remember having what looked like a locust or some other winged insect land on my chest when I was a young kid. Ever since, there have always been 5 discolored spots in this pattern ":-:". It's even shaped like something with wings. My mother confirmed that it's not a birthmark and I want to be sure my memory serves correctly. Searching the internet has only brought me information on a bug repellant that kills skin pigment. Any input would be greatly appreciated.

Can an insect kill skin pigment on contact?
Well there is one family of beetles, the Meloidae, or blister beetles which can cause skin to burn and resemble blisters. In a sensitive area of skin, it can easily leave a scar. The active chemical which they release is called Cantherodin, this is what they will secrete when disturbed.


These insects do not fly often but can, so that is possibly what landed on you.





here is a page with some images of common blister beetles:

Hope this helps!





You can maybe also try looking up Bombardier beetles, these can fire an extremely hot concauction of chemicals from their anus when disturbed.....

Reply:maybe the locust was on a poison ivy leaf prior to the landing on your chest, causing it to transport the "itchy" substance poison ivy gives off...
