Dear Bill.

I understand from your earlier comments [message #22783] that you regret there are too few photographs of Alderia modesta on the Forum. So I am sending you some recent photographs of Alderia modesta and Limapontia depressa [message #22863] taken in the field (on the saltmarshes in the south-west part of our country near estuarine coastal waters). I regularly find both species throughout the year, exept in periods when it is very cold or dry.

The animals mostly are very small in size: 2 - 3 mm and they live on Vaucheria spec.

Locality: saltmarshes in the south-west part of the country near estuarine, coastal waters, / on saltmarshes, the Netherlands, estuarine waters of the North Sea, autumn 2008, on saltmarshes on Vaucheria spec.. Length: 2 - 3 mm. Photographer: Marianne Ligthart.

With greetings:
Marianne Ligthart

Dear Marianne,

Thanks for these photos of Alderia modesta. It's nice to get in situ shots like this to give us a picture of where they both live.

Best wishes,
Bill Rudman
