Yes, these do look like Spotted Lanternfly nymphs. They are emerging and becoming noticeable in many Maryland counties now that we've warmed up. You can kill those you can manage to catch (since they run away and jump readily), but otherwise you do not need to take much action since they are so widespread in our region by now that killing a few will not make much difference in overall population size. They will not cause serious harm to garden plants, with few exceptions (grape vines and hops, mostly on commercial farms), so do not warrant any further action (like use of an insecticide).

Thanks Miri.  This is so crushing, but I will go with every little bit helps. 

You're welcome.
