They never eat because they have no mouth, and they only live for a couple of days. There are around 45 species of bees in New Zealand. All social bees are introduced to New Zealand. Social bees have long tongues so they can pollinate the flowers which native bees can not reach into. This was the reason for them being brought here.
Native bees are solitary.
They do not live in groups - they just look after themselves. They do not make honey but are important pollinators of native plants. They're only seen in summertime. There are over 100 species of wasps in New Zealand. They are also either social or solitary species.
