stages
|
 |
The various life stages of the Paralysis
tick, Ixodes holocyclus. The smallest stage, the larvae are
also known as 'seed' or 'grass' ticks, while latter stages are often
referred to as 'bush' ticks or 'shellbacks', but all of these terms
refer to the same animal. The unengorged adult female is around 4mm
long, the nymph around 2mm, while the larvae are less than 1mm.

Bite Reaction
|
|
This is a severe
allergic reaction in response to the bite of a nymphal Paralysis tick,
Ixodes holocyclus. The bite site is the red spot on the upper
arm. In some cases, the allergic reaction can be so severe that an anaphylactic
reaction may occur, which is life threatening. Deaths from allergic
reactions to tick bite have occurred in recent years. |
