Blacklegged Tick This adult female &quot;deer&quot; tick was no doubt hoping that I would provide its third bloodmeal before it overwintered. Sadly for the tick, it did not succeed. It had a black head and dorsal shield, and a dark red abdomen. Adults have 8 legs.<br />

The lifecycle of blacklegged ticks generally lasts two years. During this time, they go through four life stages: egg, six-legged larva, eight-legged nymph, and eight-legged adult. Ixodes scapularis is a three-host tick, which means that it must have one bloodmeal during each life stage (larva, nymph, adult) in order to survive. Ixodes scapularis is the main vector of Lyme disease in North America. It can also transmit other diseases such as Babesiosis, Powassan, and Anaplasmosis.

  1. Your specialty, right? Posted 7 years ago
    1. Yes - ticks and mosquitoes! Posted 7 years ago
      1. I have a "special" history with one of those creatures...malaria :( Posted 7 years ago
        1. Eek, that must be quite a memorable history. Mosquitoes were my main focus and ticks were just an added bonus :P. I focused on medical entomology because I was so amazed that such tiny and intricately beautiful creatures could also be so atrocious and lethal. Posted 7 years ago
          1. I do remember it well :) In my case the painful part was the 10 days it took for discovery after the first signs showed. Nobody, myself included, made the connection to malaria as a possible cause because we were back from Brazil for many months already. During some attacks I thought I was going to die, but people around me said I shouldn't be such a drama queen, my doctor included. Dutch doctors are harsh though, so I didn't take it personal lol.

            1. I know a couple people who have had it and they describe it similarly - feeling like you are going to die and being in intense pain. There are 4-5 different species of Plasmodium that cause malaria in humans, and the different species cause various degrees of sickness....And, the different species of Plasmodium have different incubation periods. Not to mention that taking prophylactic antimalarial drugs can delay the onset of symptoms if an infection occurs, so that symptoms may not show up for weeks or months after travel to a malaria-endemic area.

              1. It's been a long while, but I believe I had the most common species, the one that is usually not lethal yet can do neurological damage. Indeed, one shocking lesson learned was that the pills we took did absolutely nothing to get it anyway. I can ensure you that almost nobody knows this, I've checked this many times since. Tourists don't generally know this, tour operators don't know this, even some specialist in healthcare often don't know this. We didn't know either.

                I'd easily recognize it now though, the frequency of attack gives it away. It comes and goes like night and day.

                1. True, most people think the medicine will prevent infection, when in reality it just lessens the symptoms. Prophylaxis of malaria is so very complicated with drug resistant strains, combinations of medications, medication side effects, etc. It's definitely complicated and misunderstood. A vaccine can't come fast enough! Posted 7 years ago
              2. Adding a fun part to the story, to show how much misinformation there is regarding malaria, and the bad rep it has...

                I called in sick for work, reporting malaria as the cause. The sick handling is outsourced so not directly with the company. They were shocked and said "take all the time you need". The lady on the phone was almost ready to give away condolences.

                I got proper meds and returned to work 2 weeks later. I used the health broker's automated voice system to report to them that I'm off the sick leave.

                Somehow that message never got through. 8 months later they call me, very carefully suggesting if I would consider returning to work, part-time if needed.

                They thought I was on some 8 month long death bed and were too afraid to call to check on me this whole time.

                1. That is equally hilarious and horrifying! Posted 7 years ago

"Ixodes scapularis" is a hard-bodied tick of the eastern and northern Midwestern United States. It is a vector for several diseases of animals, including humans and is known as the deer tick owing to its habit of parasitizing the white-tailed deer. It is also known to parasitize mice, lizards, migratory birds, etc. especially while the tick is in the larva or nymph stage.
