In New York City there are fifty-one different types of mosquitoes. Most mosquitoes do not transmit disease and some do not bite humans at all. Some mosquitoes have the ability to spread diseases like West Nile virus. From April 1 through October 31, the city monitors mosquito populations and conducts activities to reduce the number of mosquitoes.
Monarch butterfly eggs are somewhat difficult to find in the wild. Since it only takes 3-5 days for eggs to hatch, timing is crucial. The best sign is to watch for adult Monarchs stopping at milkweed plants. A female will usually lay only one egg per milkweed plant to ensure enough food for each larva.onarch butterfly eggs are somewhat difficult to find in the wild.

The process from egg to butterfly is weather dependent and also depends on the regional climate. It can take about four weeks in the peak of the summer in warmer climates. The egg takes 5 to 10 days, the larva/caterpillar and pupa/chrysalis each take about 10 to 14 days. In winter, autumn and spring it takes a lot longer (if it happens at all â they continue to breed in Northland).
