This insect had a sweet acrid smell that I did not notice until I brushed, not the insect, but the plant it was on. After I took a couple of images I brushed my face with my hand that had touched the plant. Imedietely I noticed where I had touched my face a strong burning sensation started. I washed my hand and then face with some water and the burning slowly ceased. I then noticed another insect of the same type dripping clear liquid onto the branches and leaves below it. The color of this insect seems to serve a purpose.
