Identification and lookalikes



Many have bright contrasting hair patterns, but color varies among species. The familiar name cow killer is not evidence that the insect kills cattle.
Can velvet ants sting?
Females can deliver a very painful sting. Males lack a sting. Their larvae develop as parasitoids of other insects, often in the nests of bees or wasps.
What to do next
Do not pick up a velvet ant. Let it move away and photograph it from above without blocking its path. One wandering individual is not an ant colony requiring indoor treatment.
