Economic importance.
Eucalymnatus tessellatus
has been reported as a minor pest on ornamental plants in
California
(
Gill 1988
) and
Florida
(
Hamon & Williams 1984
).
Remarks.
Gill
et al
. (1977)
noted that the teneral adult female of
Eucalymnatus tessellatus
, without the sclerotisation of the polygonal plates, is similar to
C. longulus
(Douglas)
but differs from it by lacking subdiscal setae on the anal plates.
