Entomologists say the lack of rain means less foliage in some places and fewer spots for some insects to hatch their offspring.
"There'll probably be a population crash for a lot of different kinds of insects this year," says Steve Heydon with the Bohart Museum of Entomology at UC Davis.
He says one of those insects is a vibrant orange and black butterfly with a colorful name: "The Painted Ladies will get up here expecting to find thistle plants to lay eggs on and there just won't be any plants there."
On the other hand, it seems like we're seeing a population boom for other insects.
"Mosquitoes are definitely active now and we are seeing more of them out due to the higher than normal temperatures," says Luz Maria Rodriguez with the Sacramento-Yolo Mosquito and Vector Control District.
Other typically dormant pests that are buzzing around right now include adult house flies and stink bugs.
Rodriguez says, even with a drought, mosquito populations could thrive in some spots. For example, in the puddles of stagnant water in dried up creeks.
Record summer heat has increased fire risk in California and the Western U.S. as drought conditions expand.
Statewide water conservation exceeded the mandatory goal in May and Sacramento reduced water use 40 percent.
In the fourth year of drought in California, sales and use of "safe and sane" fireworks are restricted in some areas, allowed in others.
A California Assembly committee will hear a bill Wednesday that would allow water districts to impose taxes on any business, industry or person who wastes water.
The drought can be blamed for a number of problems and the latest is a major decline in the duck population. A new survey shows lack of rain has led to poor habitats.
