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.
Mandatory statewide water conservation rules have ended in California. But Sacramento-area users conserved 22 percent in June, compared to June 2013.
California and federal agencies say a new strategy is needed to save the endangered Delta smelt.
California is in the fifth consecutive year of drought, but state water managers ended mandatory conservation rules. Local water suppliers now determine conservation rates, and some have low or no targets. A water expert says that's 'shortsighted.'
California is in the fifth consecutive year of drought. Although mandatory statewide water conservation is over, the State Water Resources Control Board says water conservation remains a "top priority."
The California Water Resources Control Board Wednesday says Californians cut water use by 28 percent in the final month of mandatory statewide conservation.
