Insect explosion
The numbers and types of insects have exploded locally, one result of the abundant and well-spaced rainfall this summer. Quite a contrast to last summer.

But the 'explosion' has been very uneven. Some species are super abundant, while others seem to be nearly absent. Quite a confusion. Maybe all this iNat data will someday give clues as to what's happening.
The American Snout butterflies are having a banner year. The sheer numbers I am seeing of them in southeast Arizona is astronomical.

It is noted that "snout population size is positively correlated with the intensity and duration of dry periods immediately preceding drought-terminating rains".
