Thank you Lyme Disease Association for the above pictures.

 

 

 

Below you will find pictures from a fantastic group from England

1. The blacklegged ticks, I. pacificus, (depicted here), and I. scapularis, are known vectors for the zoonotic spirochetal bacteria Borrelia burgdorferi, which is the pathogen responsible for causing Lyme disease. The ticks, inoculated with the bacterium when they bite infected mice, squirrels and other small animals, subsequently pass the pathogens to their human victims when they obtain a blood meal.

2. These 'black-legged ticks', Ixodes scapularis, are found on a wide rage of hosts including mammals, birds and reptiles.
Black-legged ticks, I. scapularis are known to transmit Lyme disease, Borrelia burgdorferi, to humans and animals during feeding, when they insert their mouth parts into the skin of a host, and slowly take in the nutrient-rich host blood.

4 This is a tick of the genus Ixodes in the nymphal stage of its life cycle.
Ixodes are “hard ticks” due to the presence of a dorsal plate or scutum. There are over 200 member species of the genus Ixodes, and many of them can transmit Lyme disease to humans.

5 This illustration depicts morphologic differences found in scorpions, ticks, and spiders, all members of the Class Arachnida.
Regarding the body regionality displayed by scorpions, Scorpionida, spiders, Araneae, and ticks, Acarina, itis really based on the degree of fusion between segments that differentiates these Orders from one another.

6. This drawing shows the morphologic differences between soft ticks, Argasidae, and hard ticks, Ixodidae.
The soft ticks are oval, i.e., pear-shaped, and are rounded anteriorly, with mouth parts that are more easilyseen from the ventral view. Some soft ticks are known to be a vector for the spirochetes responsible for causing “Relapsing Fever”.

7 Members of the genus Ixodes are easily distinguished by their conspicuous anal groove, which is anterior to the anus.
When classifying ticks the location of the anal groove is important, for some Ixodidae family members are known to displaying a posteriorly located groove, or none at all, while Ixodes display a groove anterior to the anus.

8.  After laying her eggs, this female Ixodes hard tick will die, while the soft tick female will lay many batches of eggs.
The North American Ixodes are “hard ticks” due to the presence of a dorsal plate or scutum. There are over 200 member species of the genus Ixodes, and many of them can transmit Lyme disease to humans.
