Bed Bugs

Atypical feeding position. Bed bugs stayed on the cardboard and when moved away from skin, would not move forward onto skin but back up and retreat into corrugations. Front legs not used to assist in pushing stylet fascicle into skin, labium not bent, so feeding here must be shallow. See close-up insert. Red skin color is basically a birthmark, a nevus, but small red dots are from previous feeding by other bed bugs.
This feeding posture does not fit that described by Usinger (1966) Monograph of Cimicidae, Chapter 3-Bites, page 34 and figure 3-1 on page 35.

Not the typical position, bed bugs stretching and feeding and basically feeding while lying down on their backs. See close-up insert of whole bug, front legs not holding onto substrate. They haven’t used their front legs to hold onto the skin so stylet fascicle not deeply inserted into skin and labium is not bent. Red skin color is basically a birthmark, a nevus, but small red dots are from previous feedings by other bed bugs.
This feeding posture does not fit that described by Usinger (1966) Monograph of Cimicidae, Chapter 3-Bites, page 34 and figure 3-1 on page 35.

Preparing a talk for a bed bug lecture at an entomology meeting in 2010 and was able to take images with my android phone of a feeding sequence. Fed individual nymph and adult bed bugs to demonstrate bite reactions. The sequence took a little over one hour from feeding, reactions, to almost no visible reaction. I don’t experience itching. Red blotch is the nevus birthmark, not related to bed bug feeding.
