Bumble or carpenter bee

Bumble or carpenter bee

5960   I live in Modesto, California it is gloomy outside, I found this bug in my driveway this morning it was on its back moving his 4 legs like it was trying to overturn itself. I left it alone 6 hours later I go check on it and turned it over with A stick it has stripes like a bumble been and small wings on its back. I sprayed it with raid and it died. I put it in a jar I need to know what it is and should I be concerned I have small puppies.  Ellena

This is either a bumble bee (Bombus sp.) or a carpenter bee (Xylocopa sp.); the condition of your specimen makes it very difficult to be certain. Regardless, neither bee poses any threat; they are not aggressive and will sting only if severely molested. They also are valuable pollinators.  Ed Saugstad, retired entomologist; Sinks Grove, WV.
