Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

Hi All: It's been awhile since I've posted here. I hope you're all well. Is it possible to purchase a waterproof digital camera for around $200? The reason for waterproof is that I dropped one in the water for just about 10 seconds and I couldn't get it to work again.
Thanks,
Bruce

I was just thinking the same thing, I was at a camera store and looked at a couple, they all seem to start in the high 200's. I haven't done much research online tho.

Here ya go:

Pentax Optio W30 for $190

It looks like there are plenty of low prices online for the W30 and its predecessors, the W20, W10, and WPi. I've got the WPi. The link above goes to Adorama, which is a reputable merchant.

Jason,

You would know, hence my response. Would you lean toward the Pentax Optio Wxx line or the Olympus Stylus xxxSW line when choosing a waterproof camera. These two lines seem to be the main competitors in the market, and I've read reasonably similar reviews for each, so I'm sort of stumped. If you have any light to shed on the topic, it would be most appreciated. Thanks a lot.

Chris.

Hey Chris,

I really don't know, because I've only owned and used the Pentax. Olympus makes fine cameras, too. I would check out some photography review sites like dpreview.com for detailed comparisons.
