Good Sams discover exotic borer in Tarrant County
Last summer Texas Parks and Wildlife biologist, Sam Kieschnick, was going through pictures on iNaturalist and saw a picture of an insect taken by someone he knew. It was a shot of a shiny green beetle that 10-year-old nature enthusiast, Sam Hunt, had snapped in his own driveway near Eagle Mountain Lake in west Tarrant County. Something about the picture bothered biologist Sam, so he forwarded it to colleagues who were experts in a group of insects called buprestid beetles. The expert consensus seemed to be that 10-year-old… Read More →
Monarchs passing through now…don’t miss them
In case you haven’t seen your first monarch butterfly of the fall migration, you should start looking now. Mid-October is peak monarch observation month in Texas. So what is fall migration and why all the fuss about monarch butterflies? Monarchs are one of relatively few insects that have true migration. And one of the few migrant animals who instinctively travel thousands of miles to an overwintering site they have never seen before. The monarch migration starts each spring with old butterfly adults that have overwintered on a dozen… Read More →
Miller moths
If you live in the Dallas/Fort Worth area, or any other place that has had a recent outbreak of fall armyworm caterpillars, you may have noticed an increase in fast-flying, grey-brown moths. I started noticing these last week, and they appear to be growing in numbers today. If you drive early in the morning, or in the evening, you might even catch these moths in your car headlights. It’s all part of a circle of life: moths lay eggs, which turn into caterpillars, which pupate (think of a… Read More →
The surprising fall armyworm
I’ve noticed something lately. People are consistently amazed when nature intrudes on their lives, as if it’s a great exception to some law that states “nothing unusual should ever happen to me.” Whether it’s hurricanes or a snake in the house, or something as mundane as a caterpillar outbreak, the usual reaction is astonishment. That seems to be the common thread among callers this week with regard to the latest fall armyworm outbreak. I say “latest,” because fall armyworms are nothing new. According to Dr. Allen Knutson, extension agricultural… Read More →
Living with squash vine borer
A gardener recently asked me what she could do about squash vine borer. She then proceeded to list all the recommended treatments she had tried already, ranging from shooting the vines up (literally, with a hypodermic syringe full of Bt), to putting out yellow bowls to catch adult moths, to watching a gazillion videos on YouTube, to praying to the bird gods to eat the little buggers. To answer her question I spent time reviewing a new and old publications, including a new review of the literature on… Read More →
Emerald ash borer makes a move
Ever since the dreaded emerald ash borer (EAB) showed up in Arkansas and Louisiana, tree lovers have braced themselves for its inevitable arrival in Texas. Then, in May 2016, the insect was discovered in a single surveillance trap near Caddo Lake in Harrison County in east Texas. In 2017 all was quiet, with no officially reported sightings; but this summer the beetle has been found in possibly three new counties. What is EAB? The EAB is a small but powerful beetle pest–an enemy of ash trees. Adult beetles… Read More →
Insect ID via mobile device
I get lots of images in email and on the web for identification. I get to see some amazing insects and good pictures this way, but I also receive a lot of really bad insect pictures. And since bad pictures don’t help your chances of getting a successful identification, it’s in everyone’s interest to take better pictures. So here are five tips for improving your chances to get an insect identified via email, your cell phone or other mobile device. Focus on the insect, not the background. Corollary… Read More →
When ants invade
It’s ant season, and garden centers around Texas are swarming with folks looking for a quick solution to ant invasions. Ants have been the bane of humankind since before the first picnic. But who could imagine how much misery and anger a tiny little insect like an ant could produce? But of course it’s never just one ant that’s the problem. As I was recently reminded, one ant can quickly turn into dozens on the floor, on counter-tops and in the bathroom. My wife and I experienced that… Read More →
Chigger season
If my phone calls are any indication, this appears to be a whopping chigger season. Don’t know what I’m talking about? You should count your blessings. Chiggers are my personal worst nightmare. They are tiny mites, barely visible to the eye, that live on the soil surface and, in their larval stage, are parasites on humans and other vertebrate animals. Chigger bites itch terribly for 1-2 days, then slowly shrink to mildly itchy red marks that take 1 or 2 weeks to disappear. The only good thing I… Read More →
