recent bites from bed bugs
Bites from bed bug adult and nymphs. First, second instars of nymphs. Adult bed bug fed on top of left vertical-positioned vein. There was no appreciable size difference between adult and nymph bites. The initial swelling reaction subsides around 30 minutes after bites and feeding. Large red blotches on lower right at thumb base and along lower wrist are birth marks (port-wine stain or naevus flammeus), not bed-bug related.
