Snow Pool Mosquitoes and Fairy Shrimp

(Note:click on an image to enlarge it)

T-Pool

Some snow melt pools, or vernal pools, can contain tens of thousands of mosquito larvae.  These photos and videos were taken on 30 March 2015, Alpine County. “T-pool” is named for being the top of  a “T’, coming up from ‘Fairy Shrimp Pool’ (see below).

The fairy shrimp species is probably Streptocephalus sealii, as it matches the description and distribution. This distribution map is from Fairy Shrimps Of California’s Puddles, Pools, And Playas  by Clyde H. Eriksen and Denton Belk, 1999.

Esposito Pool

This vernal pool contains surprisingly few mosquito larvae, despite its large size, and this rarity of mosquitoes occurs year to year.

Bloods Meadow Pool

Bloods Meadow is home to a very large vernal pool in early spring. We find mosquito larvae all around its fringes, and in various locations within the meadow itself.

These are NOT spider bites

Although we have had reports of necrotic spider bites, the photos shown here look like they may be spider bites, but are actually MRSA sores.

For additional information, see Skin Lesions in Barracks: Consider Community-Acquired Methicillin-Resistant Staphylococcus aureus Infection Instead of – Spider Bites  by Richard S. Vetter, et. al.

 

Looks like a spider bite but is not. Diagnosed as a MRSA sore -3
