That's not a Caterpillar

Butterfly watching has me attuned to caterpillars, so when I spotted this on a dogwood leaf this evening I was excited to find out which one I had discovered.


Our Peterson First Guide didn't offer a match, so I went online to search on characteristics. That got me nowhere. Then I went to 'caterpillar maine dogwood' and up popped two images from Jim McCormac's blog entry on sawflies and yellowjackets.

It's not a butterfly or a moth, it's a sawfly. bugman clued me into dogwood sawflies on What's That Bug? which itself pointed to Penn State's Susan Parker with an Integrated Pest Management perspective and a Chris Adams entry on bugguide.net. On the latter site, danielj reports that correspondent Millie's image was a first for bugguide.net. There are others there.

This squirmy thing had climbed to the tip of a pagoda dogwood, but we've got red osiers aplenty. Time to think twice about the positive first impression?

"This is an insect you can enjoy" said Dave Smitley in his alert (PDF) for Michigan State, though he makes disclaimer about the question being asked in September.

One last (?) thing: A look at an adult from Minnesota Seasons.


Another last thing: bugguide.net genus discussion mentions four species, three in the east, two of which are common: Macremphytus tarsatus and Macremphytus testaceus.

Distance Record on AO-92

On 2019-02-20 at 13:08Z, EB1AO and I completed a 4,936-km QSO between IN52pe and FN43rg, setting a distance record for the U/v repeater on AO-92. It was a -11° pass — Celsius (12°F… brrr). Really, it was a 1° pass — maximum elevation at my end. Jose's map tells the story, though the time reported is his AOS , not QSO time. We both recorded the contact. Mine is in Dropbox: eb1ao_AO-92.wav . Thanks EB1AO. Thanks AMSAT-NA . UPDATE: Our record was surpassed by F4DXV and VE1VOX, who added 75 km to the distance, in August 2020.

Bird of the Year Poses Typographical Challenge

The American Birding Association's selection of the ʻiʻiwi as its 2018 Bird of the Year poses a typographical challenge: What to do about the ʻokina? That "single quote" at its start, and right between the i's, is one of two Hawaiian diacritical marks . It denotes a glottal stop, a quick throat-catch like that in uh-oh, so ʻiʻiwi is pronounced ee-EEvee . The ʻokina appears once in the main heading of the Bird of the Year page, but is omitted throughout Nate Swick's explanation of why the honeycreeper was chosen. This inconsistency is avoidable and the omission is undesirable. The ʻokina is not optional punctuation but a purposeful letter. The ABA isn't awkward alone. The Birds of North America account at the Cornell Lab of Ornithology spells ʻiʻiwi three ways (unique treatments in heading and citation, main text, and image caption). The American Bird Conservancy gives this bird two marks but resorts to the straight quote (prime) rather than employing

One White Heron

A 2-ounce packet of an organic black tea, Dubliner's Breakfast, from White Heron Tea of Portsmouth, New Hampshire, found its way into my Christmas stocking. Santa knows. I inferred this would be a hearty, rich brew, that would brace me for morning. Dubliners are Irish, no? Instead, I tasted a nuanced, fruity cup with less kick than anticipated or desired. The packet went into the afternoon collection, taking an honored place in the rotation especially when the mood was more cerebral than kinetic. Three and a half stars.
