Aleyrodidae nymph

Aleyrodidae nymph
Plymouth Rock, Winneshiek County, Iowa, USA
July 18, 2011
Size: 1 mm
I found 3 of these on the back side of 2 leaves of goldenrod. Pretty much flat on top with some rippling and a little orange spot (mouth?) at one end. It is whiter than this photo shows. Also there is what appears to be the larval shed just off the posterior end

I don't think it's a good idea to put these in a genus without an expert opinion.

Looks like something in Aleyrodidae
Some sort of whitefly I believe. I would think nymph.


 
I do believe you are correct.
But this is confusing me, an inmobile nymph with no wing starts? There's nothing under "info" to explain this. Help! I'm a simple person and I need to understand this.

 
They have an interesting lifecycle.
Whiteflies have a weird type of metamorphosis that isn't holometabelous ( egg, larva, pupa, adult) or paurometabolus (nymphs that develop wing pads). They have a pupal stage that isn't a true pupa, so nymphs don't always show that distinct development of wings unless they're in the pupal stage. I don't think they're truly immobile although the first instar is most active and other instars are considered sessile, and they tend to stick to one are of the plant as they feed. They tap into the plant juices so why would they move? :)

 
Thank you.
You just made whiteflies much more interesting.
