The first rule of finding insects is “Look on flowers.” Flowers provide a place to rest, as well as a place to eat and be eaten. The second rule is “if you see an insect that’s really still (or in an odd position), look for a predator nearby.” So, when the BugLady spotted a horizontal horse fly, she knew that something was afoot, and she soon located the ambush bug above and to the left of the fly (the fly’s eyes were a bonus).
A few years ago, when the BugLady wrote about the ninebark leaf beetle (Calligrapha spiraea), she made a mental note to pay more attention to ninebark (Physocarpus opulifolius) during its blooming period. Ninebark? The way the BugLady heard the story, the shrub’s name comes from the German word “nein” for “no,” a reference to the fact that the smooth bark of the young branches looks like no bark at all (some non-German botanist eventually rearranged the vowels so that they made sense to him).
It’s quiet now, but the Viburnum leaf beetle (Pyrrhalta viburni) is slowly chewing its way across southern Wisconsin. It has followed the general invasive species template – establishing small, often undetected populations and staying below the radar for years, its spread (unwittingly) aided by human activity. Once we know we know it’s here, it has already reached numbers that are difficult to control.
Greetings, BugFans, Seasoned BugFans know that the BugLady can’t go too long without writing about Odonates. Quick review: Dragonflies and damselflies are in the order Odonata. Dragonflies tend to be bigger and bulkier than damselflies, with wrap-around eyes that touch …
Greetings, BugFans, The BugLady had fun in a rabbit hole recently. OK, it was a cold, gray day, threatening snow/rain, and the light from the monitor was brighter than the light from outside, but it’s a rabbit hole she had …
This summer, the BugLady got a “what is this?” email from BugFan Debra that contained a picture of this beautiful black wasp with white spats that she took in northern Wisconsin (thanks, Debra!). The posture was reminiscent of our local Giant Ichneumon wasps, but there are only four species in that genus, and this wasn’t any of them. So, the BugLady suggested that Debra send the picture to the entomology department at UW-Madison, where almost-BugFan PJ identified it. He noted that its “dapper black & white appearance is pretty distinctive” and ID’d it as Xorides stigmapterus.
Howdy, BugFans, Here’s an updated BOTW from 10 years ago (more words). Whirligig beetles are referred to in Kaufman and Eaton’s Field Guide to Insects of North America as the “bumper cars of the beetle world.” Looking like dark watermelon …
Another week, another zebra. The BugLady had fun chasing this dynamite little insect along the banks of the Milwaukee River at Waubedonia Park in mid-summer (it likes to perch on the undersides of leaves). She had never seen one before, but after a few false starts, she discovered that it’s a Zebra Caddisfly.
The BugLady photographed these beautiful caterpillars on a cold and blustery day at the start of October, a day when nearby New England asters were topped by sluggish bumblebees (bumblebees are sometimes called, only half-jokingly, a “warm-blooded bees”). The caterpillars weren’t too active, either. They’re called Zebra Caterpillars (of course!),
Once again, the BugLady fell for an insect’s disguise. It sure looked like a sluggish yellowjacket sitting on a raspberry leaf, and it wasn’t until she took a picture of it that she noticed all of its hairs/scales. The Raspberry crown borer/Blackberry clearwing borer is a moth in the Clear-winged moth family Sesiidae.
