A year containing an extra day. It has 366 days instead of the normal 365 days. The extra day is added in February, which has 29 days instead of the normal 28 days. Leap years occur every 4 years. 2016 is a leap year and so is 2020. Except that every 100 years special rules apply.
Best Answer: A average life span is about 1 year. Some live only 3 months, but others can live up to a couple of years. The lifespan of the average tick is about two years. Source(s): http://www.nyc.gov/html/doh/html/ehs/ehs... A fly is 3 days so i'm guessing somewhere around the lines of there.
Ticks have four life stages: egg, six-legged larva, eight-legged nymph and adult. After the egg hatches, the tiny larva (sometimes called a âseed tickâ) feeds on an appropriate host. The larva then develops (molts) into the larger nymph. The nymph feeds on a host and then molts into an even larger adult.
