An experimental cogitation in Western Washington found that out of more than 2,400 pollinator visit to flush at urban and rural farms about 35 % were made by flies – most of which were the calamitous - and - yellow - striped syrphid fly front , also called hoverflies . For a few plant life , including pea , kale and lily , flies were the only pollinator watch . Overall , bees were still the most common , accounting for about 61 % of flowered sojourn , but the rest were made by other insects and spiders .
" We find that there really were a spectacular phone number of pollinator call blossom that were not bee , " pronounce Rae Olsson , a WSU post - doctoral associate and lead author of the survey release in Food Webs . " The majority of the non - bee pollinator were fly , and most of those were syrphid fly which is a radical that ordinarily mimic bees . "
Syrphid tent-fly ' bee - like colors believably help them avoid predators who are afraid of getting stung , but they are lawful fly ball with two backstage as fight back to bees which have four . The fly might have additional benefits for plants , Olsson add together , since as juveniles they eat pestis like aphids . As grownup , they consume nectar and chat heyday so have the potential to move pollen the same way that bee do , though it is less knowing than bees who roll up pollen to feed their vernal .
" Bee populations are declining , and we are trying to help them , but there ’s elbow room at the table for all the pollinators , " Olsson said . " There are a lot of preservation and monitoring effort for bee , but that does n’t extend to some of the other pollinators . I think the great unwashed will be surprised to receive that there are a peck more unlike types of pollinating insects – all we really need to do is to embark on paying a little more attending to them . "
The study also noted pollinator differences between rural and urban spaces . reflection sites in urban areas show a greater diversity of pollinator corresponding with the wide range of plant life grown in city gardens and smaller - sized farm . Rural farm with their larger fields of plants had a greater abundance .
For every cultivator , urban or rural , who is interested in increase the number and multifariousness of pollinators visiting their fields or garden , Olsson recommended increase the variety show of bloom plant life . reach sure that something is bloom all throughout the season , even if on the boundary of a field , will support the biodiversity of pollinators because their dissimilar lifespan stages materialize at different times of the class .
" Some pollinator like certain butterfly and moths are only present in a pollinating form for a small period of time , " Olsson said . " They may only dwell for a few day as adults , so when they emerge and are quick to pollinate , it ’s salutary to make indisputable that you have something for them to eat . "
