I see what looks to be two different insects. The one with dots looks like a first stage Spotted Lanternfly nymph. The first link below provides close up photos to confirm if this is what you are seeing. Destroy any you find. The pest will go through several growth stages and looks before reaching adult form in the late summer/fall. Some egg cases may not yet have hatched so you can scrape and kill those if any remain. The first link has photos of what to look for at each stage. Spotted lanternfly (SLF) is an invasive insect that has spread throughout Pennsylvania since its discovery in Berks County in 2014. SLF feeds on the plant sap of many different plants including grapevines, maples, black walnut, and other important plants in PA. SLF can be controlled with a combination of physical removal of life stages, host trees (Tree of Heaven) as well as pesticide applications. As SLF feeds, the insect excretes honeydew (a sugary substance) which can attract bees, wasps, and other insects. The honeydew also builds up and promotes the growth for sooty mold (fungi), which can cover the plant, forest understories, patio furniture, cars, and anything else found below SLF feeding. This insect is easily moved if no one is looking.  You are in the quarantine area so a “look before you leave“ strategy is in effect. Inspecting your vehicles, trailers, or any outdoor items before you move around or out of the quarantine is important.  If possible, don’t park in tree lines and keep windows rolled up when you park your vehicle.  Know the life stages of the insect and when to look for what. The homeowners guide below includes a variety of control options tailored for different stages. Chemical controls may not be necessary but if that option is used, apply only insecticides that are registered by the Environmental Protection Agency (EPA) to treat the specific insect on your property. Home remedies should not be used against SLF because they may be unsafe to humans, pets, and plants and could be illegal. https://extension.psu.edu/have-you-seen-a-spotted-lanternfly https://extension.psu.edu/spotted-lanternfly-management-for-homeowners We thank you for your question and wisH you good luck.

Thank you so much for your helpful response. It turns out that the SLF image you showed me is exactly what we have and we will proceed with efforts to kill and have our tree treated if necessary. I’m hoping the tree can be saved as it is huge and our deck was built around it- Regarding the second insect whose picture was too blurry- I will attach a better photo and see if that works. I thought it was a small black flying insect But the magnified image shows color and markings. That’s the one that feasted on me. I trapped and killed them in a bowl of apple cider vinegar and dawn soap- but any other mitigation advice would be much appreciated
