Are you crazy about prairies or at least prairie curious? Do you have a friend or kid you’d like to introduce to the prairie? Are you hungry to learn more about bees or bobolinks? Have you always wondered what that one plant is that you see along the road?

Come join us on July 9 at The Nature Conservancy’s Platte River Prairies south of Wood River, Nebraska as we jump back into in-person field days! The event is completely free and open to all ages.

The day will officially start at 8:30am, followed by four sessions that will each provide multiple options for topics. Those topics will include bird identification and ecology, plant identification, wetland ecology, seed harvesting, prairie ecology, small mammals, prairie invertebrates and more. You can choose where to go for each session. We will wrap up the day by about 2:30pm, but you can come and go whenever you like.

If you want to get up extra early, there will be two ‘pre-session sessions’. Nic Salick (The Nature Conservancy) will be leading a bird hike at 7am. In addition, Mike Schrad (Nebraska Master Naturalist) will be – weather permitting – checking his small mammal traps at 7am and welcomes anyone to tag along to see what he catches. In fact, if you’re in the area and want to come out to help him set his traps (live traps) the previous evening, there will be an opportunity for that as well.

I’ll share more detailed information soon, including a full agenda and location information, but for now, please put Saturday July 9 on your calendar and plan to come see us!

If you look closely at wildflowers, you’ll often see insects moving around and between them. Many of those insects, of course, are bees, flies, butterflies, moths or other pollinators. While these small creatures are eating resources created by the plants they visit, they also provide services in return. The insects get pollen and/or nectar to feed themselves or their babies but also (unintentionally) facilitate the fertilization of ovaries that allow plants to produce seeds. It’s a pretty good trade all around – though with lots of variation in terms of how much each side benefits from the other.

All of that makes a pretty good story of cooperation among the earth’s creatures, but the full picture is much more complex. A strong percentage of insects hanging around flowers provide no benefits to the plants, and many do considerable damage instead. For today, I’ll ignore the predators who use flowers as hunting grounds, even though they are infinitely fascinating. Instead, I want to feature a few examples of ‘freeloading’ insects who take and take from flowers, but never give anything back. …Or at least don’t give back to the flowers.

Numerous beetle species feed on flowers, eating pollen and nectar, but also petals, anthers, and other vital anatomical features. Some of these beetles can provide pollination services if they move between blossoms, but that benefit can often be outweighed by the destruction they create. Depending upon the number of beetles working over a flower, that level of destruction can be minor or catastrophic for a particular plant.

That doesn’t make these beetles evil or deserving of our dislike, however. Beetles have a right to make a living too, and there are plenty of flowers for everyone in a prairie (or even a garden) that’s well-managed. In fact, as I argued in a recent post, providing flowers to feed beetles and many other creatures should be part of our role as gardeners and land managers. Beetles play all kinds of vital roles in ecosystems, so keeping them around is certainly a good thing (excepting invasive species like Japanese beetles, of course, which can create far more devastation then benefits.)

Grasshoppers, katydids, and crickets represent another group of insects that are often found chomping on flowers. These little scamps feed on multiple parts of the flowers, but they probably provide even less accidental pollination than beetles do. However, like beetles, this group of long-legged buggers is really good to have around. If nothing else, they are a major food source for birds and many other small predators (and there’s much more to them than just that but that’s another post). Instead of getting mad at grasshoppers for eating flowers, we should be expressing gratitude to plants for creating enough flowers to support grasshopper populations!

Caterpillars and similar-looking larvae of flies, beetles, and other insects are also commonly-found feeding on flowers. As with beetles and grasshoppers, the result can be pretty negative for individual flowers, but – again – the sacrifices made by those plants help support the broader ecosystem. Caterpillars are another huge food source for other animals and the vast majority end up as food rather than moths, butterflies, or other adult insects. They might as well enjoy a good meal while they can, right? I’ll also admit my personal bias here, since my favorite insect in the world is a little flower-eating caterpillar.

Sometimes, the way insects utilize flowers is less obvious than a big ol’ caterpillar chewing on the anthers and pollen of a sunflower. Loads of insects use flowers as a place to lay eggs, many of which hatch out and then feed on the flower – often hidden from our view. Others, like the giant robber fly pictured above, apparently lay eggs in flowers only so their larvae can drop off and burrow into the soil to chase down beetle larvae (thanks beetles!). So why do they lay their eggs in flowers and not in the soil? I have no idea.

More commonly, insects laying their eggs in flowers because that flower will provide both their home and their food source once they hatch. Some of those larvae eat parts of the flower itself, but many feed on the developing seeds, taking advantage of those highly concentrated packets of nutrition. If you peel open the head of a thistle or sunflower after it has stopped actively blooming, you’ll often find a few tiny ‘grubs’ chewing on the seeds within.

Once again, you could denigrate those larvae and their parents as pests if you like, but you’d be missing the larger picture. Those blossom-chompers and seed-munchers are part of the incredibly complex and interconnected web of prairie life. The give-and-take relationships between flowers and insects have existed for millennia and will continue for many more. This spring and summer, as you wander prairies, gardens, and other places where flowers bloom, consider paying a little extra attention to who else is enjoying those same blossoms. Those other visitors will undoubtedly have stories worth learning.
