Dianthidium texanum
Texas Pebble Bee
Dianthidium texanum is a species of resin bee in the family Megachilidae, commonly known as the Texas Pebble Bee. Native to North and Middle America, this solitary bee constructs nests in pre-existing cavities such as hollow twigs or beetle borings, using resin to partition cells and seal the nest entrance. The species has been documented in bee block monitoring studies and is known to be parasitized by leucospid wasps. Adults are active during summer months and visit flowers for nectar and pollen.
