What is a red insect with a black ring called?

More information is needed. Check whether it is really an insect, with six legs, or a spider with eight legs. Many ants and wasps have red colouring with black bands. Spiders are more likely to be predominantly black with a red marking. Describe whether or not the creature has wings. Explain where the black ring is located, and its position, e.g. whether it encircles the creature, or whether it is a round mark on one side. Being more specific will increase your chances of getting an answer.
