    Anyone know how long a newly hatched nymph can live without a bloodmeal and how far can they travel to get one? Any idea where I can find this kind of info? I've read that an adult can travel 100 feet. Is the same true of a nymph who has not fed yet? What kind of condition can an egg not hatch in? Only extreme heat of 115 F or more or freezing conditions?

    All temp dependant. There is no overall answer.

    The hotter it is, the shorter the lifespan without food.

    I found out the nymphs can live for months and adults over a year

    True and false on both counts. Look at the temp effect on the times. From the BB bible.

    1st instar nymphs that did feed once survived 275 days at 50F and 17 days at 99.
    From the Monograph...all stages fed once before sealing away.

      Life..................Starvation
      Stage................Survival at Temp
      Temp....50F..........65F..........81F........99F
      1...........274.6.......113.6.......27.8.......16.8
      2...........398.9.......171.1.......45.6.......30.4
      3 ..........412.7.......214.4.......71.2.......35.3
      4 ..........432.5.......234.1.......73.3.......37.2
      5 ..........484.9.......161.4.......39.5.......32.6
      AF .......425.0.......277.1.......86.7.......31.9
      AM.......401.9.......175.6.......43.4.......28.6

    If they haven't fed it will be drastically less.

    I've kept hatched & unfed first instar nymphs at regular room temp (upper 60s-low 70sF) and at least 6 weeks can go by and the bugs are still alive. Some people have kept them longer. Of course, some have also died during this time period.

    but this is a common statement that you can find on many web sites, in the news, quoted over and over again by everyone, but with no clarification. Insects are temperature dependent and also as spideyjg pointed out with the table above the bugs had been fed once and then kept at different temperatures. Those reared at low temperatures last longer, either fed or unfed. If fed, obviously will be able to last longer.

    WOW, thanks. These are just what I'm looking for to understand the nature of this problem.

    I wonder how far the 1st or even 2nd instar nymphs can crawl to find a meal. When they are sealed away, they may not crawl around wasting energy.
