Bug o’the Week – Big Sand Tiger Beetle

Last fall, BugFan Joanne told the BugLady about a fabulous tiger beetle she saw in the dunes at Kohler Andrae State Park, and the BugLady was determined to find one this year. Tiger beetles are a wonderful group in the Ground beetle family Carabidae. They’re varied and beautiful (and surprisingly cryptic); they’re unapologetic predators as both larvae and adults; and they have a bunch of very cool adaptations – big eyes, excellent eyesight, long legs, and massive jaws that allow them to live and hunt pretty much out in the open. Tiger beetles have a lot of fans.

Bug o’the Week – Red Velvet Mite Again

We’re in the trough between Christmas and New Year’s Day. No-one knows exactly what day of the week it is, but whatever is on TV is sure to be a rerun. This BOTW is, too (well – a few new words). And a few corrections – when she posted the original episode in 2011, the BugLady threw in a few extra “h’s” where there aren’t supposed to be any – she misspelled both the (probable) family and the genus. They should be Trombidiidae and Trombium.

The BugLady has forever been amazed by Red Velvet Mites. Is there anything more unlikely than a wee arachnid that looks like a plump, brilliantly red plush Beanie Baby (though the BOTW series has been filled with the “unlikely”)? But seriously, why would a critter that dwells in soil and leaf litter bother to be so fancy?

Bug o’the Week – The Twelve Bugs of Christmas 2022

Wow! The 10th annual installment of The Twelve (or Thirteen) Bugs of Christmas! The Bugs of Christmas features shots, taken throughout the year, of insects and spiders who have already had their own BOTW, but who posed nicely.

It’s time once again to celebrate a year of bugs with this baker’s dozen collection of the beautiful, the odd, and the mysterious. Gifts. Right under our noses. All the time.

Bug o’the Week – Two Stink Bugs

The BugLady thinks stink bugs are cool and she loves finding species she hasn’t seen before. This year, she saw two new ones – the first one in a sand dune, and the second in a bog – but she suspects that habitat is secondary in the stink bugs’ game plan to the availability of food.

They’re called “stink bugs” because they have glands in the thorax that produce, as Eric Eaton says in the Field Guide to Insects of North America, “volatile aromatic compounds sure to repel all but the most desperate predators.” One author adds that “Stink bugs can smell pretty bad. Even my hens turn up their beaks when one crawls by…..”

Bug o’the Week – Tall Flea Beetle

Sometimes, the BugLady gets a surprise as she’s researching an insect, and that was the case this week.

She saw a cluster of these pretty beetles when she was on a boardwalk in a wetland. Their pedigree? They are leaf beetles in the huge family Chrysomelidae; within that family, they’re in the tribe Alticini – the flea beetles, and they are (probably) Disonycha procera (Disonycha means “double-clawed”). There are 470 members of that tribe in North America, and more elsewhere. Only one source gave it a common name, but there was no explanation why this small insect might be called the Tall flea beetle.

Bug o’the Week – Mottled Sand Grasshopper

From July into September, the Creeping Juniper Nature Trail at Kohler Andrae State Park is ruled by grasshoppers, and the BugLady had lots of fun chasing them around this summer (she stayed on the boardwalk, of course) (well, until the Swamp Darner flew past). She especially liked the aptly-named Mottled sand grasshopper (Spharagemon collare). MSGs are not restricted to Lake Michigan dunes, they have a range that stretches from Arizona and New Mexico diagonally back through the northern Great Plains and the Great Lakes, and well into Canada. Plus, inexplicably, North Carolina, Delaware and Maryland. Within that wedge of North America, they’re found in sunny, sparsely-vegetated areas with dry, sandy, and/or disturbed soils. They’re especially common along the edges of wheat fields, says Wikipedia.

Bug o’the Week – Autumn Meadowhawk Dragonfly

We’ve just had an all-too-brief Indian Summer – it got warm enough for the flies to fly, the tree crickets to sing, and yes, for a few very late Monarch butterflies to drift past on their big journey. The BugLady spent some time on boardwalks in wetlands, enjoying the last dragonflies of the year.

Meadowhawks, in the Skimmer family Libellulidae, are a genus of 15 species, nine of which have been recorded in Wisconsin. They can be tricky to identify (understatement). They start to appear in late June/early July and are with us for the rest of the summer and well into fall, but other than a few tenacious White-faced Meadowhawks, the final meadowhawk on the scene is the Autumn Meadowhawk .

Autumn Meadowhawks (Sympetrum vicinum) can be found in Southern Canada and much of the US, except for the northern Rockies, the arid Southwest, and a few of the Gulf States. Some meadowhawks are picky about habitat, but not Autumn Meadowhawks, which are equally happy in shallow, permanent ponds, lakes, marshes and swamps, bogs, flooded meadows, and even slow-moving streams, especially if there are woodlands nearby.

Bug o’the Week – Entomophagy 101 Redux

The BugLady’s first experience with entomology (well, except for the fresh-from-the-garden earthworms she consumed when she was 8) (they do not taste like chicken) came when someone gifted her family with a little box of chocolate-covered insects from a novelty store. No one ever opened it. Her first serious exposure to the idea of eating bugs came when she spent a week at the Audubon Camp in Maine. One of the camp’s teachers mentioned that he had eaten ants, and while the small red ones were too spicy for him and the large black ones were too bland, the species that are red at one end and black at the other were, like the Baby Bear’s bed, just right. The BugLady didn’t hear the term “entomophagy” until at least three decades later.

“Entomophagy” simply refers to the use of insects by humans as food (notwithstanding the fact that an “extract” of a scale insect called the cochineal bug provides a natural red dye called “red dye E120” or “carmine” that is widely used in food products; and that the FDA standards for food purity allow five fly eggs or one maggot per can of fruit juice and 400 insect parts per 0.22 cup of ground cinnamon). Used broadly, the term includes spiders and millipedes, but it does not include invertebrates like crayfish that are already part of our cuisine. Eggs, larvae, pupae and adults may be used, depending on the species. Some insects are eaten in recognizable form, but if staring into your food’s compound eyes isn’t your cup of tea, some insects are ground into “flour.”

Bug o’the Week – Red-belted Bumble Bee

Greetings, BugFans,

Isn’t this a pretty bee!!!

When you aim your camera at a bumble bee, which the BugLady does frequently, you expect to see black and yellow in varying proportions (the vaguaries of wind plus the bees’ perpetual motion results in lots of bumble bee shots on the cutting room floor).

The BugLady photographed this bee on the prairie at Forest Beach Migratory Preserve. Her name is Bombus rufocinctus – the Red-belted bumble bee – and she’s a bee with somewhat northern inclinations plus a few disjunct eastern locations and minus the Great Plains. RBBBs are bees of open spaces like grasslands, and they also like parks, gardens, barrens, and quarries. They are widespread but not common across their range (they make up about 10% of Wisconsin bumble bee records), and they’re found here mainly in the southern half of the state, though historical data suggest that they once occupied all of it.

Bug o’the Week – the Missouri Bee-killer Robber Fly

Howdy, BugFans,

Robber flies are a very cool bunch of flies that we have visited a number of times in the past. Besides being awesome-looking, these “bearded” flies (sometimes called Assassin flies) are predators, and they are not shrinking violets. In the Field Guide to the Insects of North America, Eric Eaton says that “Robber flies (family Asilidae) are to other insects what falcons are to other birds.”

Robber flies’ modus operandi is to spot an insect from their perch, grab it (and they will go after insects larger than they are), inject it with saliva to both kill it and soften its insides, and then perch and ingest the liquid through a tube called the hypopharynx. They eat lots of insects that are agricultural pests, but they haven’t been formally deployed as biological controls because they are equally likely to eat honey bees and Monarch butterflies.
