Bug o’the Week – Dogwood Scurfy Scale
Howdy, BugFans,
If asked to describe a Red-osier dogwood shrub, lots of people would say “it has red bark with white lumps on it.” It does – but it doesn’t.
Some of our most un-bug-like bugs are the scale insects. There are lots of them worldwide – about 8,400 species in 36 families. They’re called scales because they (the females, anyway) cling, limpet-like, to their food plant, protected under a waxy covering that looks fish-scale-ish. They’re sexually dimorphic (“two forms”), and adult males – in the species where males exist – are often tiny and gnat-like. If your basic definition of an insect is “six legs, some wings, and three body parts that are divided in segments” you’ll have to suspend it a bit for the scales.
