​Late Season Pollinators: Supporting Beneficial Insects in Autumn

 By: Mandy Hatman

​As the vibrant colors of summer fade into the warm hues of autumn, many gardeners in Louisiana might think the time for pollinators has passed. However, fall is a crucial season for many beneficial insects, and our gardens can play a vital role in supporting them.

Why Late Season Pollinators Matter
Many species remain active well into the fall, and some are just reaching their peak. These industrious insects are essential for:

• Pollinating late-blooming plants
• Building up energy reserves for winter
• Laying eggs that will become next year's pollinators

Louisiana's Autumn Pollinators

• Bees: While honeybees are less active, many native bee species are still hard at work. Look for bumblebees, sweat bees, and mason bees.
• Butterflies: The iconic Monarch butterfly migrates through Louisiana in the fall. You might also spot Gulf Fritillaries and Cloudless Sulphurs.
• Moths: Often overlooked, moths are important nighttime pollinators. The Luna moth and various sphinx moths are active in autumn.
• Flies: Yes, flies! Hoverflies are excellent pollinators and remain active in cooler weather.

Plants That Support Late Season Pollinators
To help these beneficial insects, include these native Louisiana plants in your garden:

• Goldenrod (Solidago sp.): A favorite of many bee species
• Asters (Symphyotrichum sp.): Attract butterflies and bees
• Joe Pye Weed (Eutrochium fistulosum): Loved by butterflies
• Ironweed (Vernonia sp.): Attracts a variety of pollinators
• Mistflower (Conoclinium coelestinum): A butterfly magnet

Creating a Pollinator-Friendly Fall Garden

• Provide a Water Source: A shallow dish with pebbles makes a perfect insect drinking station.
• Avoid Pesticides: These can harm beneficial insects. Use organic pest control methods instead.
• Leave the Leaves: Many pollinators overwinter in leaf litter. Leave some areas of your garden "messy" for their benefit.
• Provide Shelter: Leave hollow stems standing and create brush piles for overwintering insects.
• Plant in Clusters: Groups of the same plant make it easier for pollinators to find and feed efficiently.

By supporting late season pollinators, we not only help these crucial insects survive the winter but also ensure a healthy start for our gardens come spring. So this fall, as you're preparing your garden for winter, remember to leave a little something for our tiny, hardworking friends. Your spring garden will thank you!
