Take part in The Great Kiwi Bee Count
5 reasons to love honeybees.
Gardeners and schoolchildren are being invited to participate in NZ Gardener's annual citizen science survey of bee numbers in New Zealand.
The Great Kiwi Bee Count is like a digital census for bees and the trends it reveals will help apiculture scientists learn more about how bees and other pollinators are doing in New Zealand.
Throughout September, Kiwis young and old are encouraged to get into their gardens, parks or neighbourhood – preferably on a sunny day – find a plant that's in flower, go to The Great Kiwi Bee Count on your smart phone or tablet and count how many bees and other pollinators they see over a two minute period.
The Great Kiwi Bee Count includes photos of 12 different bees and pollinators which will help you ID whatever insects you see... in fact doing the Great Kiwi Bee Count is a great way to learn more about the bugs living in your backyard.

Stocking up to feed their larvae is why bumblebees are interested in pollen. The way they gather it is remarkable: the foraging female bumblebees grab a flower and then vibrate their wings at an almighty pace to dislodge the pollen from the anthers. Clouds of pollen swirls around the flower and some falls right on top of the target, kicking off the fertilisation routine. Tomatoes and other solanaceous crops simply love this kind of vibratory attention – that’s why bumblebees are commercially available to gardeners and commercial tomato growers alike.
The fact that butterflies regularly visit flowers (for a quick feed of nectar) is a great indicator that their actions are beneficial for the distribution of pollen. The unfurled proboscis constantly probes to find the nectar source, gathering the grains by accident, while the feet pick up a fair amount of pollen too. Curiously, those butterfly feet are also able to "smell" or "taste" the flowers and nectar. Different butterfly species prefer different types of flowers.
Our native bees tend to sip nectar too, usually from flowers that have an open nectar reservoir (manuka, pohutukawa and such species), but their real intention is gathering pollen to provide for their larvae, deep inside their tunnels in the soil. Judging from the numbers of native bees in late spring and summer, their pollination potential must be considerable in the New Zealand landscape. We have a couple of dozen species in just about all the major native habitats, right into the alpine zones of our mountains, and some have adapted themselves well to exotic plant life too.
Most people don't recognise hoverflies as flies. They hover here, there and everywhere, usually near or above pollen-rich flowers. The cool thing is that some of these hoverfly species lay their eggs among aphid colonies, where the fly’s larvae (let’s call them maggots) will feast on these small sucking insects. Blowflies are also implicated in pollination services. The brown variety is particularly active in urban gardens, especially when the resident dog is let out at regular times of the day. Handy things, those blowflies, and very proficient at multi-tasking.
The narcissus-bulb fly maggot can do some damage, but the elegant, adult fly is a pollinator that resembles a small bumblebee, with similar colouring and fuzzy hair. Experienced gardeners know that adult flies differ from adult bumblebees in a few important ways: the flies only have one pair of wings (most other insects have two pairs) and they don’t sting, which allows you to gently catch them with your hands and impress the kids with your daring trick!
