It’s easy to find insects in July.

Aphids in Schenley Park are expanding from plant to plant along the gravel trails, sucking the juice out of Jerusalem artichokes (Helianthus tuberosus).

Yellow hawkweeds (Pilosella caespitosa) are attracting bee-like insects.

And some insects are unseen but have left evidence behind. Can you see two kinds of insect evidence on this crabapple tree?
