Don’t fret over whitefly infestations on flowers as these latecomers to the landscape most likely don’t require control because they won’t make it through the Illinois winter. Only plants that make the journey back inside should be monitored and or treated for these insect pests.

Fall armyworms in hand

The larvae of a moth may be wreaking havoc on your lawns right now and could be exacerbated by the lack of rain leaving behind lots of dead grass in its wake. Recent sightings of large fall armyworm infestations of turf have been reported in Bloomington Normal this week.

They are annoying, pesky, and won’t leave you alone. They look like little bees. Most people think they are sweat bees because of their black and yellow stripes but they don’t sting despite their extremely offensive behavior during the latter part of the summer. Regardless of their interactions with us, it is the covert interactions with the environment that make them standout insects in Illinois. Here are three things you didn’t know about Hover Flies:

Summer is officially here, and it’s time to get out to your favorite walking or hiking spot! That may entail walking through tall grass and woodland brush, depending on where you go.

Monarch Caterpillar and Butterfly

BLOOMINGTON, Ill. – The state insect, the monarch butterfly, is facing a crisis. Each May, Illinoisans celebrate the monarch butterfly, but University of Illinois Extension Horticulture Educator Kelly Allsup says that Illinois residents should be worried.

They are crawling on my windows, walls, and houseplants newly rescued from the lower night temperatures of the fall and creeping me out. They could be hanging out on your dishes, doing a balancing act on your toothbrush, resting in your clothing or hair, or be a rather interesting ornament on your Christmas tree. 

A recent study tracking butterfly abundance in Ohio over the last 20 years has discovered a 33% decline. We can only assume that in Illinois we have similar patterns in decline in our butterfly populations. Scientists believe the decline may be attributed to climate change, habitat degradation, and agricultural practices.

You have likely spied upon, or even befriended, praying mantises in your garden this growing season. Although most adults die out during the late fall and early winter, they have likely left behind a foamy garden ornaments within your landscape.

Females can start laying eggs as soon as you see adults. Once the adult flies are discovered, management decisions should be made. Adult flies are tan with red eyes and a tiny 2-3mm-long (up to a one-eighth of an inch). Males have characteristic dark spots on their wings that can easily be seen with a magnifying glass. Adults live for up to 2 weeks, and females can lay up to 300 eggs. Development from egg to adult can occur in as little as eight days, and 10 or more generations may occur within a season.

Did you know that with minimal investment, you can open a hotel? Insect hotels offer places for beneficial insects and pollinators to survive winter's chill and to nest in spring and summer. You can use them to employ garden warriors in any flower bed, vegetable garden, or fruit orchard.
