I think this might be another Maccaffertium.

Description

Note - the accompanying images show 2 different specimens, which I believe to be the same species, both females. One is seen in image imgp0493 and 0494, the other in images 0505 2, 8659, 8657, and 8636. If you look closely at image 8657, you'll see what appears to be a mass of eggs inside the abdomen.

Whitish body, wide-set, light-colored eyes. Small dark dots on side of abdomen. Translucent wings with dark cross veins. 2 tails.
Compare this with observation 874281, which seems to be a different species. That one is perhaps a mm or 2 smaller than this. 874281 seems to have darker tails, markings on legs, and eyes (also different shape of eyes/head). Also different patterns on the wings.

This may also be a Maccaffertium.

Description

Note the images are of 2 different specimens, a male (images imgp0488 and 489) and a female (imgp491). They were mating. The other female is seen in images 515 2, 516, and 8636. If you look closely at image 516, you'll see what appears to be a mass of eggs inside the abdomen.

Size 14-16. Both have dark eyes, whitish body with a bit of dull orange at end of abdomen and on thorax (male in particular), dark stripes on sides of abdomen. Male has particularly long forelegs and tails. 2 tails. Leading edge of wings have a darker brownish area (still translucent) near the top - especially in the male.

Compare this to observation 874304.

I believe these are Maccaffertium, but not entirely sure.

Description from Wikipedia

Mayflies or shadflies are insects belonging to the order Ephemeroptera (from the Greek εφημερος, ephemeros = "short-lived" (literally "lasting a day" "daily" or "day-long"), πτερον, pteron = "wing", referring to the brief lifespan of adults). They have been placed into an ancient group of insects termed the Palaeoptera, which also contains dragonflies and damselflies. They are aquatic insects whose immature stage (called "naiad" or, colloquially, "nymph") usually lasts one year in fresh water. The adults are...
