About a week and a half ago these guys started appearing in our house in the keys.. They are very attracted to light and their numbers increase at night. Is it a long horned something? They have a little yellow near head but are otherwise black- see picture. Thank you 🙂

We concur that this is a Longhorned Borer Beetle in the family Cerambycidae, but we are having trouble providing you with a species name. We will contact Eric Eaton and Arthur Evans to see if either can identify your Longicorn to the species level.

This is a false blister beetle (Oedemeridae), Oxycopis thoracica (p. 365 in BENA).
Ed. Note: According to the book Beetles of Eastern North America by Arthur V. Evans: “Adults on flowers of palmetto (Sabal palmetto), New Jersey tea (Ceanothus americanum), aster (Seriocarpus), etc.” Additional images are available on BugGuide. Of the family, BugGuide notes: “Most abundant along the coast and in moist wooded habitats. Adults of some species are nectar and pollen feeders and often found on flowers. They are also found resting on foliage or in moist, rotten logs. Larvae develop in moist, decaying logs, stumps, and roots of hardwoods and conifers, including wharf pilings and driftwood.”
