Threats to Texas Bumblebees

We all know about colony collapse disorder whereby colonies of European honeybees seem to vanish.

Less well known are the threats facing a lot of our native bumblebees.

Michael Warriner is an invertebrate biologist with a soft spot for native bumblebees. Like other native wildlife species in Texas, habitat loss is taking its toll on native bumblebees.

Bumblebees need open, flower-rich habitat—like grasslands. And, a lot of that habitat’s been converted to agriculture.

Warriner says pesticide use is another concern, but the threats to these big black and yellow insects doesn’t stop there.

And also, there’s been the importation of bumblebees from Europe into this country which has brought in parasites and diseases that may be impacting them. So, there’s a lot of concern how they’re faring in North America.

One of the threats to Texas bumblebees might actually be honeybees, which have colonies in the tens of thousands compared to the hundreds of insects in a bumblebee colony.

Honeybees have these tens of thousands of workers, and so they can go out and monopolize a flower resource—like nectar or pollen—and that reduces what’s available for our native bees. And there’s some research that suggests that the presence of honeybees in natural sites can reduce native bees.

We’ll have the potential impact from bumblebee decline tomorrow.

Texas Pollinator Bioblitz

Thursday, October 6th, 2016
Save the Pollinators

Participate in the Texas Pollinator Bioblitz this month and #savethepollinators.

This is Passport to Texas

Calling all citizen scientists. We want you to participate in the Texas Pollinator BioBlitz, October 7th through 16th.

[We have] two goals in mind: to increase awareness about pollinators, and about the habitat that they require.

Johnnie Smith is Texas Parks and Wildlife Conservation Education Manager. Pollinators include bees, butterflies, beetles, moths and other critters that move pollen while foraging.

If you participate in the pollinator bioblitz, you’re going to have an opportunity to observe pollinators at a site that you visit, like your local zoo or aquarium or nature center. And observe the pollinators that are there. Grab a picture of the pollinators you find, and you can post them onto Instagram. We’re asking all of the participants to use the hashtag #savethepollinators.

State parks offer pollinator observation opportunities, too. And, you can also post findings, on iNaturalist.org. Texas Parks and Wildlife’s website, has pages dedicated to the Pollinator Bioblitz.

Where people can learn what pollinators might be in their area. Links to what might be blooming in your area right now—that’s hosted out of the Wildflower center—and then also, to be aware of habitat you have that supports pollinators. And if you don’t have habitat in or near your home, school library… We’re encouraging people to try and get organized in planting pollinator habitat.

The Texas Pollinator BioBlitz is October 7 through 16. Participating is as easy as stepping outside.

Monarch Malaise

Habitat loss along its migration route may be one reason the Monarch butterfly is in decline. While feeding on nectar, Monarchs pollinate wildflowers along their route, which benefits our ecosystem.

There are two primary ways that habitat supports pollinators.

Johnnie Smith is Texas Parks and Wildlife Conservation Education Manager.

And one is, the adult pollinators oftentimes feed on nectar of flowers. So, flowering plants that are a food source for the pollinator is very important. But also, is the food source that the pollinator’s larvae rely on as they’re growing up and becoming an adult. And so, that is just as important as the flowering plants that support the adults.

For Monarchs, native milkweed is an important plant. By cultivating them in our yards, along with other nectar and larval plants, we can all play a part in their survival.

There is no effort that is too small to be counted worthy. And there’s no spot of land that is too small to contain pollinator habitat. So, we really want to empower everybody—that they can make a difference. Right where you stand. Right where you live—you can create pollinator habitat, and help turn around this negative trend with the monarchs.

Tomorrow: the Pollinator Bioblitz, an event to build awareness to help all pollinators.

Flowers, Boxes, and Bees. Oh My!

Looking for pollinators on backyard flowering plants.

Looking for pollinators on backyard flowering plants.

This is Passport to Texas

Texas Parks and Wildlife developed a new protocol that addresses land management for pollinators. While the protocols focus on acreage, urban dwellers can still manage for these species in their backyards.

One of the biggest things that urban residents can do is simply plant more good quality flowering plants.

Michael Warriner is non-game and rare species program leader for Texas Parks and Wildlife. He says native plants are best, but noninvasive nonnatives are also useful. He adds that if you’re serious about helping pollinators—scale back your lawn.

And having more flowering plants. Also, another thing is offering nest sites. And especially with our native solitary bees that nest in dead wood, urban folks can put up native bee nesting blocks.

If you’re worried about putting up nesting boxes because of the close proximity it puts you to bees—don’t.

Because solitary bees don’t defend their nest sites, you don’t have to worry about these bees flying out and defending their nests and getting stung. Let’s say like honeybee colonies do. Or, paper wasps. You know, insects that are social.

By planting more flowering species in your landscape, and by hanging bee nesting boxes in your public outdoor spaces, you are not only providing food, shelter and breeding sites for important pollinators, you’re also creating a more beautiful setting for yourself. Win-win.

Milkweed for Monarchs

Milkweed for monarchs

Milkweed for monarchs

This is Passport to Texas

More than seventy species of milkweed have been recorded nationwide; over half of those are native to Texas. Including two that are endemic.

These are species that are found nowhere else but within the Texas border. One of them is called Texas Milkweed, which is found in canyons in Central Texas. And then we have a species called Coastal Milkweed that occurs roughly from the Houston area to just north of Brownsville.

Jason Singhurst, a botanist with Texas Parks and Wildlife, says milkweeds provide sustenance to the iconic monarch butterfly during its migration.

So, here in Texas, we know certain species like green milkweed, antelope horns, broadleaf milkweed, and zizotes are some of our most abundant species that we’re seeing monarch larvae and adults visit.

Because milkweed species vary, do monarchs use each species in the same or different ways?

That’s a really good question. That’s something we’re trying to figure out in Texas. And that’s why we started this mapping project called Texas Milkweeds and Monarchs project—using iNaturalist. It’s an app that you can download on your smartphone. We’re using that project to help us identify different species of milkweeds across the state, and then also which species that larvae, or adult monarch butterflies are visiting.
