Thank you for creating a new page, Charley...

This task was actually on a seriously old "to do" list of mine and I think I just completely forgot about it. Thanks for following through!

Sminthurinus quadrimaculatus forma bipunctatus

The recent introduction of the forma bimaculatus page at BugGuide by Harsi Parker was a nice opportunity for me to look again over all the availmble pictures.
It turns out that your specimen is not forma bimaculatus but a different colour form called bipunctatus.
The difference between the two colour forms:
in bimaculatus, 2 separate white 'eyebrows' are distinctly visible
in bipunctatus, the white eyebrows are interconnected forming a kind of white forehead.

Sminthurinus quadrimaculatus

forma bimaculatus.
Typically, this species has 4 white spots on its body. This form with just 2 spots is rare.
The white 'spots' on the body are in fact small elevations of the skin.
Great pictures, Joyce!

Lots of variation in this species! Thanks for explaining the white spots.
