Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

Dorsal view of a Epeorus albertae (Heptageniidae) (Pink Lady) Mayfly Nymph from the East Fork Issaquah Creek in Washington
This specimen keys to the Epeorus albertae group of species. Of the five species in that group, the two known in Washington state are Epeorus albertae and Epeorus dulciana. Of the two, albertae has been collected in vastly more locations in Washington than dulciana, suggesting it is far more common. On that basis alone I'm tentatively putting this nymph in albertae, with the large caveat that there's no real information to rule out dulciana.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

"When scaled to body length and compared to 227 other acoustic species, the acoustic energy produced by Micronecta scholtzi appears as an extreme value, outperforming marine and terrestrial mammal vocalisations" (from the online journal, PLoS ONE . Link goes to original article.

From the article:

Here we report for the first time the acoustic behaviour of Micronecta scholtzi (Fieber, 1860), a common aquatic bug that produces an extremely loud courtship song. This insect is a few millimetres in length yet can produce sound audible from the riverside. This suggests the emission of intense signals departing from the body size to amplitude rule.

Before I found my wife and she settled me down, I was known to do the same thing when the cutie-pies in their bikini's slid by in their canoes on the good old Au Sable...:) "Hey fisherman! Are you having any luck today?" "That depends sweetie...Where you girls camping this evening? I have a bottle of Gavi chilling in that feeder spring over there...I could bring it along and we can sing Kum-by-ya around the fire tonight..."

The first TroutNut who makes a wise crack about "a few millimetres in length" will get his ears boxed...;) Especially if it's Tony!

Spence -

Not wanting my ears boxed, I'm going to stay away from millimeters (whether true or not). However, did those bikini clad cutie-pies cause any emission of intense acoustic signals departing from the body size to amplitude rule?

In a manner of speaking...;)

Do I detect just a wee bit of self consciousness?

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

Allan,

As you may recall, Dr Ziggy Freud once said, after he noticed his audience staring at his cigar..."You must remember, that sometimes a cigar is just a cigar..." ;)

"wee bit"...Is that metric as well?

It depends on just how many millimeters we are talking about here - a few, or a few hundred?? Size does matter...

;oD

A few astronomy jokes here, which for some reason I've never seen exploited on a t-shirt or bumper sticker:

"How many inches do YOU have?"

"Astronomers stay up ALL NIGHT!"

No matter how big the one you just caught is, there's always a bigger one out there somewhere...
