Case of the Week 590

This week's fascinating case was donated by Dr. Graham Hickling. He captured the following scene that he entitled "Hatching". What are these newborns?

    Six legs, newly hatched, long club shaped palps, apparently no visible festoons and no visible inverted U anal plate. Definitely newly hatched seed ticks (I would like to suggest a name change to TICK-ETTE) as in pick up your tickettes here. You might need to FLAG them down.

    My diminishing vision allows me 2 possibilities..... Ixodes if anal grove is present, or Amblyomma if festoons ate present.

    Once more a very timely reminder from Dr. Pritt. At this time of the year as the weather warms up, these nymphs emerge from their eggs in droves and they are hungry to feed. These ticks nymphs are also ready to serve as mobile vectors for quite a number of infections.
    For sure at the magnification these pictures were taken, it is not possible to adequately identify these baby ticks.

    These are larval ticks, not nymphs.

    Ixodes scapularis larvae. The body proportions argue against Amblyomma, IMHO

    Thank you Eagleville, I did check again and they have six legs. As such they are larvae.

    Let's say that they are larvae of Ixodes sp. Apparently under the light during filming, they became even more active.

    Forgot to add what a wonderful photo and movie. Gives me the creeps just watching those hatchlings run about.
