Water strider found in a freshwater swampy lake in northeastern PA today 6-26-13. Never saw a red one. Our common one is Gerris, which are black ( and larger) but we never saw a red one. This one is about 3/4 the size of a an adult Gerris.

When we read your subject line and saw the thumbnail attachment, we suspected a phoretic mite colony on the Water Strider, but upon enlarging the photo, that does not appear to be the case. We don’t know why this Water Strider is red, but it does not seem typical. The lack of wings indicates this is an immature specimen, hence its smaller size.
