an insect has 6 legs
A black insect with orange legs that digs in the dirt is known as a mud dauber. It is similar to a wasp, except not aggressive.
ant
some kind
A black bug with 6 legs and antenna is likely an insect. Insects are characterized by having three body segments (head, thorax, and abdomen), six legs, and usually one or two pairs of antenna. The color black is a common coloration for many insect species.
Silver fish are actually a wingless insect, so moves round on legs.
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.
