This is a great showcase. A lot of pollinators. Is this going to be organized somehow?
I've got a collection of a couple hundred or so pictures that I'd like to see organized by eco-services or plant relationships instead of biological classification.
BTW: You don't need an expensive zoom, if you can find a decent magnifying glass to hold out in front of your lens.
The way I understand the pollination/beneficial situation for gardeners and farmers goes something like this:
Honeybees are efficient pollinators, but usually stick to one or two sources for a season. So they're good for monocultures and near
trees and orchards.
Bumblebees are the best all-around pollinators because they have lots of hairs and are the sloppiest eaters. They have to visit a lot of flowers everyday. They have really long tongues to get into flute flowers. Like all 'wild' bees they like the edges.
Solitary bees like
Masons, carders, diggers, furrow and leaf-cutter bees are great generalists, too. They live in walls,
wood or the ground. Good for medium and large sized flowers but they can work the tiny flowers on any umbels that can hold them up.
There are lots of
tiny parasitic wasps that need those umbels with the tiny flowers (like the parsley family). Some of these wasps lay eggs in
pests like stinkbugs and caterpillars,
Cuckoo bees pollinate the small flowers but their larvae eat their host bee larvae.
Yellow and black
wasps are general predators of bees, flies, spiders and bugs. Some are good, some aggressive. No hair, so they don't pollinate much.
The yellow and black striped, smooth-skinned flies (colored like wasps) are
Hoverflies. The hairless adults eat nektar or pollen, but their larvae eat as many aphids, sometimes mosquito larvae in
water, as voraciously as ladybugs.
Ladybugs and
Lacewings are great for aphid control, both in adult and larvae stages. Neither really pollinate (no hairs).
Butterflies and
moths are okay pollinators, but their babies can be voracious caterpillars. Not bad if you have birds or big wasps.
Dragonflies are tyrannosaurus of the sky. They can eat anything flying, and lots of them.
There are also types of
parasitic fly that stick their eggs on bugs and beetles, which soon hatch and turn the pest into lunch, keeping their populations down. I don't think they're major pollinators, but beneficial.
And
Ground Beetles are pretty hungry for slug eggs, fallen plantbug eggs, anything near the ground at night.
The big obstacle is their number and variety depending on where you live. Maybe one day.
