Hungry bumble bees make plants flower early by cutting holes in their leaves

A hungry bumble bee cuts a hole in a leaf, stimulating the plant to flower early.

When bumble bee queens emerge from hibernation, they need to gather pollen and nectar to start their new colonies. If they wake up too soon, there may not be enough flowers in bloom. Now, researchers have discovered the bees have a way to order some fast food: They nibble holes in leaves, spurring plants to blossom weeks ahead of schedule. Many questions remain about the details of this strategy and how it evolved.
“It’s certainly surprising,” says Lars Chittka, a behavioral ecologist at the Queen Mary University of London, who was not involved. “We’re only at the beginning of exploring this phenomenon.”
Researchers at ETH Zürich chanced upon the discovery when they noticed curious bite marks on leaves while studying how bees respond to plant odors. They had added bumble bees to a research greenhouse and observed them cutting holes in the shape of half-moons. What was going on? At first, the researchers thought the insects might be feeding on fluid from the leaves, but the bees didn’t stay long enough to get much. Nor did they appear to be taking any part of the leaves back to their colonies.
A key observation—that bumble bees from colonies with less food were more avidly damaging the leaves—suggested another goal. The researchers wondered whether the damage triggered the plants to flower sooner, providing pollen to the hungry pollinators. After all, some plants speed up their flowering when they are stressed by disease or drought because these threats provide an incentive to reproduce sooner. But no one had ever shown that a pollinator can stimulate flowering. “I thought it was a long shot,” recalls Mark Mescher, an evolutionary biologist at ETH Zürich who co-led the research.
The researchers set up a greenhouse experiment with black mustard (Brassica nigra), a crop they had been studying. Ten plants were put in mesh bags with bumble bees that hadn’t eaten any pollen for 3 days; they proceeded to nibble five to 10 holes in each plant. On average, those plants flowered after 17 days; undamaged plants that had not been exposed to bumble bees took an average of 33 days, the researchers report today in Science. In a similar experiment, tomato plants sped up their flowering by 30 days. “The magnitude of the effects is huge,” Mescher says.

Wildflowers

This past Saturday Drew and I went to Buena Vista in Bancroft Wi.. It is a very long drive to go there but it is always worth going there. When we got there we had to wait out a ran storm for about a half hour before we could really drive around to look for birds and wildflowers. We have bird pictures and wildflower pictures. So today I am going to post the wildflower pictures and then tomorrow I will post the bird pictures.

I was thinking of something to post for some time now and I decided to go through all of my wildflower pictures and pick out some of the better pictures to post from over the years. I will be starting with when I first started taking the pictures back in 2012. Yes I have been taking the pictures to share with everyone for four years and I can't even believe this.

This is a picture of the very first Water Lily I had ever taken and the picture was taken at Tichigan Wildlife Refuge in Tichigan Wi  on 6-3-2012. I have seen the flower before but never took a picture of it until this day.

This is the first time I ever seen or heard of this flower it is the Yellow Monkey Flower this picture was taken at Meyers Park in Racine Wi on 8-17-2013.

This is a picture of a Wild Rose this picture was taken at Richard Bong State Recreational Area in Brighton Wi 6-28-2013. I remember this day it was raining and yes we are crazy enough to go out in the rain to get some pictures.

This is a picture of a Perennial Pea this picture was taken on Shelter Valley Rd in Forest County 7-4-2014. This is one of the times we went up north and took one day to go out driving around looking for pictures of birds and flowers.

This is a picture of a Crested Dwarf Iris this picture was taken at Richard Bong State Recreational Area in Brighton Wi 6-17-2015. This is one of my favorite flowers to go looking for.

This is a picture of a Crinum Timeless Lily this picture was taken at Whitewater University College in Whitewater Wi 7-6-2015. I was there my daughter had an appointment so her step sister and I went driving around the campus looking at the flowers to get some pictures. her step sister and I had a blast just driving around the campus and we almost go ourselves lost. Why sit in the parking lot bored when you can drive around.

I hope everyone enjoys the pictures I just thought this may brighten up you day and hope that Spring comes soon.
