Bug o’the Week – American Emerald Dragonfly

Greetings BugFans,

The dragonfly season is starting – migrant Common Green Darners and Variegated Meadowhawks are filtering into the state, and visions of sugarplums (in the form of Chalk-fronted Corporals, Baskettails, and Eastern Forktails) are dancing in our heads! June will see the first of the Emeralds (family Corduliidae).

Bug o’the Week – Oblique-banded Leafroller Moth

Howdy, BugFans,

Oblique-banded Leafrollers (OBLRs) are in the family Tortricidae (accent on the first and third syllables), sometimes called the Tortricid/tortrix, leaf roller, and leaf tier moths. It’s a large group (10,000 species worldwide and 1,400 north of the Rio Grande) of small (wingspans of ½” to 1 ¼”), drab, bell/arrowhead-shaped moths, and even smaller caterpillars that are often green with dark heads. Some species are agricultural pests (spruce budworm and a variety of apple-lovers), and a few species are used as biological controls to deal with unwanted plants. Caterpillars of some Tortricid species bore into plant materials, and others feed on the exterior (and these caterpillars come equipped with a structure called an anal fork that allows them to flip their frass (bug poop) away from their bodies, so it won’t lead parasites or predators to them). Some are generalist feeders and some limit their diets. A few make galls.

Bug o’the Week – Green Lacewings

Howdy, BugFans,

These lovely, fragile-looking insects have fluttered around the edges of several BOTWs over the past 17-plus years, and it’s time for them to have an episode of their own.

Bug o’the Week – The Cicadas are Coming – a Tale in Four Parts

Greetings BugFans,

The insect world is gearing up to stage an event that is the entomological equivalent of the recent total solar eclipse. The buzz (if you’ll pardon the term) began a few months ago with articles in the New York Times and the Smithsonian newsletter. The event: the emergence of billions (with a “b”) of Periodical cicadas over a large chunk of the country south and east of Wisconsin. What one entomologist calls a “spectacular, macabre Mardi Gras” and another calls “a David Attenborough show in your backyard.”

Bug o’the Week – Bugs without Bios XIX

Howdy, BugFans,

Bugs without bios – those humble (but worthy) bugs about whom little information is readily available.  Today’s bugs check those boxes as species, but they have something in common – their lifestyles are similar to those of close relatives who have already starred in their own BOTW.

Bug o’the Week – The Monarch Butterfly Problem

Howdy, BugFans,

The BugLady wrote this for an upcoming newsletter of the Lake Michigan Bird Observatory (an organization that would love your support). It started out as a simple report about this year’s survey of overwintering Monarch Butterflies, but then it took the bit in its teeth and became oh-so-much more. Put your feet up.

Bug o’the Week – Tobacco Budworm

Greetings, BugFans,

The BugLady photographed this handsome moth on her back porch rail last summer, and she was temporarily mystified when she identified it as a Tobacco budworm moth, because the nearest tobacco farm is probably more than 100 miles west of her. Then she found an alternative common name – the Geranium budworm – and since she is the Geranium Queen, it made more sense (and it explained the frass on the bookshelves).

Bug o’the Week – Cylapus tenuicornis Plant Bug

Howdy, BugFans,

One day last August, the BugLady pulled her mail out of her mailbox and saw this little bug sitting on a newspaper, and she managed to take a few shots of it with her purse camera before it departed. She had never seen it before. If BOTW had an “Obscure (but Cute) Insects” category (and many BugFans might argue that it already does), this bug would be right at home there.

Bug o’the Week – Burrowing Wolf Spider

Greetings, BugFans,

One afternoon in late June as the BugLady was walking along the cordwalk at Kohler-Andrae State Park, she noticed a few half-inch-ish holes in the sand, holes that had more “structure” than the ones she makes with her walking stick, and larger than those made by solitary wasps.  She took a couple of throwaway shots and was very surprised when she put one up on the monitor and noticed eyes and legs!

Bug o’the Week – And Now for Something Different – Cattails

Howdy, BugFans,

Wanted: Colonists to settle in wide open spaces. Must be adaptable, able to put down roots in submerged or soggy soil, and stand firm in the face of wind and waves, rodents and carp. Temporary accommodations only.

It turns out that cattails are ideal candidates for this not-so-attractive job description.
